Here is the deal, I have a Apk file, just can run on android phone. Now I take the Apk I want,  decompile it or do something can change Apk file to Jar file. Jar file will be a java execution, can run on pc with java software. Are people understand? So, how to do it? Is it possible?
I tried running Android 4.1.1 in VirtualBox, but it was too slow and sluggish to do anything. I came across Windroy which runs Android as a Windows app, but it won't run Google Play.  I want to run this on my laptop.  Any help would be greatly appreciated.
What are underfull hboxes and vboxes and how can I get rid of them? Often, TeX outputs underfull hbox and vbox warnings when running and in the generated log file. What are these and how can I get rid of them? I would be happy to get some hints on the following integral: $$ \int_0^1\frac{x^{19}-1}{\ln x}\,dx $$ Prime ideal in a polynomial ring over an integrally closed domain Wavy stream of liquid What is the connection between regularization and the method of lagrange multipliers ? To prevent overfitting people people add a regularization term (proportional to the squared sum of the parameters of the model) with a regularization parameter $\lambda$ to the cost function of linear regression. Is this parameter $\lambda$ the same as a lagrange multiplier? So is regularization the same as the method of lagrange multiplier? Or how are these methods connected? If we minimize the Wasserstein loss, $$W_1 (P_S, P_T) = \underset{\gamma \in \Pi}{\text{min }} \sum_{x,y} |x-y|\gamma(x,y)$$ which means we are looking for the coupling $\gamma(x,y)$ that minimizes the cost of moving mass from the source distribution $P_S$ to the target distribution $P_T$,  Do the masses of the source and target distributions have to be identical? If so or not, how are the masses of $P_T$ and $P_S$ accounted for mathematically in, or when minimizing, the shown formula, or what might be missing/overlooked by the Wasserstein approach overall due to the mass differences? My actual question is to find the number of transversal given a collection of set ...  After a little bit of study it has come down to:  How can we count the number of matchings in a bipartite graph with parts of size $m$ and $n$ such that it covers all $m$ vertices of the first part, $m \le n$?  I already know that there is a way to count the number of perfect matchings in a bipartite graph with $m=n$ using the permanent of its (square) incidence matrix. What can a wizard take instead of a familiar at 1st level? The familiar is brilliant feature for a wizard, but not for a prestige multiclassing one. Such a wizard stops upgrading his familiar once getting off the main road. So if he still wants to utilize his familiar, he should take the obtain familiar feat, but this would made the basic familiar feature redundant.  So what options can a wizard take instead of gaining a familiar at 1st level? How do I detect running processes using a library package? This command is doing the rounds for detecting currently running processes using glibc:  lsof | grep libc | awk '{print $2}' | sort | uniq   I find it intensely annoying, since /libc/ matches not only libc, but on my system:  /lib/x86_64-linux-gnu/libcap.so.2.24 /lib/x86_64-linux-gnu/libcgmanager.so.0.0.0 /lib/x86_64-linux-gnu/libcom_err.so.2.1 /lib/x86_64-linux-gnu/libcrypt-2.19.so /lib/x86_64-linux-gnu/libcrypto.so.1.0.0 /usr/lib/libcamel-1.2.so.45.0.0 /usr/lib/unity-settings-daemon-1.0/libcolor.so /usr/lib/unity-settings-daemon-1.0/libcursor.so /usr/lib/x86_64-linux-gnu/colord-plugins/libcd_plugin_camera.so /usr/lib/x86_64-linux-gnu/colord-plugins/libcd_plugin_scanner.so /usr/lib/x86_64-linux-gnu/gtk-3.0/modules/libcanberra-gtk3-module.so /usr/lib/x86_64-linux-gnu/libcairo-gobject.so.2.11301.0 /usr/lib/x86_64-linux-gnu/libcairo.so.2.11301.0 /usr/lib/x86_64-linux-gnu/libcanberra-0.30/libcanberra-pulse.so /usr/lib/x86_64-linux-gnu/libcanberra-gtk3.so.0.1.9 /usr/lib/x86_64-linux-gnu/libcanberra.so.0.2.5 /usr/lib/x86_64-linux-gnu/libcap-ng.so.0.0.0 /usr/lib/x86_64-linux-gnu/libck-connector.so.0.0.0 /usr/lib/x86_64-linux-gnu/libcolordprivate.so.1.0.23 /usr/lib/x86_64-linux-gnu/libcolord.so.1.0.23 /usr/lib/x86_64-linux-gnu/libcroco-0.6.so.3.0.1 /usr/lib/x86_64-linux-gnu/libcupsmime.so.1 /usr/lib/x86_64-linux-gnu/libcups.so.2 /usr/lib/x86_64-linux-gnu/samba/libcliauth.so.0 /usr/lib/x86_64-linux-gnu/samba/libcli_cldap.so.0 /usr/lib/x86_64-linux-gnu/samba/libcli-ldap-common.so.0 /usr/lib/x86_64-linux-gnu/samba/libcli-nbt.so.0 /usr/lib/x86_64-linux-gnu/samba/libcli_smb_common.so.0 /usr/lib/x86_64-linux-gnu/samba/libcli_spoolss.so.0 /usr/lib/x86_64-linux-gnu/samba/liblibcli_lsa3.so.0 /usr/lib/x86_64-linux-gnu/samba/liblibcli_netlogon3.so.0   I understand that libc is used by pretty much everything, but I'd like to refine this command. Consider its applications for other libraries. How can I do this?  The flaw in this approach, in my opinion, is that the package providing libc may include a whole host of other shared library files (all of which may or may not be covered under the umbrella term that is the library name, like glibc, or libboost-python). Using a word boundary or - to mark the end of libc doesn't really fix this. This may not be a flaw, perhaps, as Braiam points out, since many or all of these .so files may link to a core file in which the flaw resides, as is the case for libc6 on Debian.   If a specific OS/distro is needed, assume Debian Linux.  Also annoying is that this command could be condensed to lsof | awk '/libc/{print $2}' | sort -u. How can I extract a page range / a part of a PDF? Do you have any idea how to extract a part of a PDF document and save it as PDF? On OS X it is absolutely trivial by using Preview. I tried PDF editor and other programs but to no avail. I would like a program where I select the part that I want and then save it as a PDF file with a simple command like CMD+N on OS X. I want the extracted part to be saved as PDF and not as JPEG, etc. Can I use grep matches to execute command? I need to upgrade php from 5.3 to 5.4. I've installed it with rpm. I want clean install: delete all 5.3 packages, and install all necessary 5.4. Here is the command to see all installed packages:  rpm -qa |grep php   It prints out a list of packages, and I want to remove all them with:  rpm -e *pakage.name*   Can I iterate over all matches in grep results and use each match in:   rpm -e *grep.match* Prove any orthogonal 2-by-2 can be written in one of these forms.... I'd like to prove that any orthogonal $2 \times 2$ matrix can be written   $$\bigg(\begin{matrix}    \cos x &amp; -\sin x  \\     \sin x &amp; \cos x   \end{matrix}\bigg) \hspace{1.0em} \text{or} \hspace{1.0em} \bigg(\begin{matrix}    \cos x &amp; \sin x \\    \sin x &amp; -\cos x \end{matrix}\bigg)$$  for $0 \le x &lt; 2\pi$.  I have no idea how to do this. I feel like this is something I've missed and is really straightforward but I can't find it in my book... Fish vs Fishes for plural use Now, I encountered a sentence in a text book, saying     Many fish are specially adapted to live only in certain places.   I know that plural of the word fish can be fish as Merriam says    But wouldn't it someway or somewhat sound unusual or "too unique"?  Is it only to me? Is it time for Stack Exchange, Inc and the community to legally separate amicably? There's no need to  the  that have led to a lack of trust between  of  and . Suffice it to say that astoundingly they continue to assert that  and, instead of apologizing and reinstating Monica have demanded that she go through a process with no transparency, due process, or involvement from the community.   Has the time has come for Stack Exchange, Inc to spin off the community and all the data needed to keep the sites running to a separate non-profit, who would then in turn license the software from the company?  What's in it for the community?   The community can practice self determination for issues from as basic as the number of moderators they have to as fundamental as the policies they enforce. If the company development continues to be unresponsive to the community's needs, the community would be able to develop its own open source software that would meet its needs. They can find their own funding model instead of having ads imposed on them.   What's in it for the company?   Community actions will no longer reflect on the company. Interaction with the community as a customer may come more naturally to current leadership than the present paradigm. They don't have to worry about paying for the community's operating expenses. They can focus on doing one thing well. How do I edit my profile? This is probably a noob question, but I forgot how to edit my profile.   Can anyone help me? There is no visible button for me. Python List vs. Array - when to use? If you are creating a 1d array, you can implement it as a List, or else use the 'array' module in the standard library.  I have always used Lists for 1d arrays.  What is the reason or circumstance where I would want to use the array module instead?  Is it for performance and memory optimization, or am I missing something obvious? Is it possible to append to innerHTML without destroying descendants' event listeners? In the following example code, I attach an onclick event handler to the span containing the text "foo". The handler is an anonymous function that pops up an alert().  However, if I assign to the parent node's innerHTML, this onclick event handler gets destroyed - clicking "foo" fails to pop up the alert box.  Is this fixable?  &lt;html&gt;  &lt;head&gt;  &lt;script type="text/javascript"&gt;    function start () {     myspan = document.getElementById("myspan");     myspan.onclick = function() { alert ("hi"); };      mydiv = document.getElementById("mydiv");     mydiv.innerHTML += "bar";   }   &lt;/script&gt;  &lt;/head&gt;   &lt;body onload="start()"&gt;    &lt;div id="mydiv" style="border: solid red 2px"&gt;      &lt;span id="myspan"&gt;foo&lt;/span&gt;    &lt;/div&gt;  &lt;/body&gt;  &lt;/html&gt; Passing parameters to a document I compile most of my documents via Makefiles which take care of the bibliography, indexes, etc. Often I'd like to compile different versions from the same TeX file changing only small things (e.g. a beamer presentation plus a version with the handout option).  Is there any standard mechanism for passing parameters to the TeX file so that I can just type make handout to get the handout version in the above example? Why can't I join a friend's world on Minecraft PE? I'm on my tablet playing Minecraft PE. My boyfriend rang me and asked me to join his Minecraft PE world. However, I can't do it because the game doesn't show his world. What's wrong and how can I fix it? How to show $a,b$ coprime to $n\Rightarrow ab$ coprime to $n$? Let $a,b,n$ be integers such that  $\gcd(a,n)=\gcd(b,n)=1$. How to show that $\gcd(ab,n)=1$?   In other words, how to show that if two integers $a$ and $b$ each have no non-trivial common divisor with and integer $n$, then their product does no have a non-trivial common divisor with $n$ either.     This is a problem that is an exercise in my course.   Intuitively it seems plausible and it is easy to check in specific cases but how to  give an actual proof is not obvious.
