Android app installers are .apk, so I assume that is what you mean. If so then put it anywhere, go to your security settings and turn on the option to install from unknown sources (for better security turn it off again when you are not using it), then use any file browser to find your apk and click on it. That should start up the app installer.

I assume you got the apk from a trustworthy source. That's important as the main malware infection route in Android is trojans, apps that have malware hidden in them.
 
Yes thanks . I found that I could put the ".apk" file on the SD card when inserted it in my PC . Then when I put it back into the phone I simply selected it and it loaded fine .
Thats interesting on sources . If following a project like I am on instructables I will of course be vulnerable .

The .apk file is a zip type file containing an executable binary it seems and the source is an ".ala" file I suppose.
Is there any way I can de-compile the" .apk" file to reveal the source?

If you want the actual source code, I think trying to decompile an Android binary wouldn't reveal the source code any more than trying to decompile say a Windows EXE would. An APK is basically a ZIP archive.
 
Well a quick web search on "decompile apk" would reveal a number of options. As long as you can read the code that results it might help you, though if someone wanted to beat such a check there would surely be ways (trivial ones would include the app having to download other resources after installation, with those containing the malware rather than the apk itself, or providing a "clean" app for install and then putting malware into an "update" at a later date).

But by and large the best bet is to be careful where you get stuff from. You can avoid the worst risks by applying some simple rules, e.g. sites that provide "cracked" apps for download, and sites where anyone can upload stuff, are very high risk. Also any app suggested by spam, by an unsolicited pop-up of any sort (the OS never recommends downloading boosters, antivirus, etc), and anything that is downloaded in the background while you are browsing something else, should be avoided at all costs.
