Install Games-Apps manually on Android -APK

Android is one of the most promising mobile platforms currently available on the market. Many more new Android smartphones are expected in the coming year and they are getting more and more powerful. One of the best features of the Android OS is the availability of third party applications.

Here’s how you can install APKs (.apks are Android packages) on your Android device directly, bypassing the Market. Be warned though that there exists apps outside the market that would gain access to your private details. Before installing any apps, read the warning as to what phone data the app will be accessing before your decide to push through.
1. Make sure you allow apps from unknown sources to be installed. Go to Settings > Applications and check Unknown sources. 2. Transfer your .apk file to your SD card. You can simply connect it to your PC to copy the files. Or if the file’s not too big, send it to your Dropbox or E-mail and access it from your phone (if you do it this way, no need for step 3).
3. Since I copied a game onto my microSD, I need to access it from the phone. I downloaded a file manager (Astro) and browsed to my APK. Some phones like Samsung already have a built-in file explorer. If you have Documents to Go or any other apps that can open documents, you can also use that.
4. Found your APK? Good, just click it to open.
5. Read the warning. Everything looks kosher? Good? Go ahead and click Install.
