• Android developers can restrict their apps to certain devices and minimum versions of Android. If you want to bypass the device restrictions, you'll need to root your Android phone. On the other hand, if you download an app that requires a higher version of Android, update your device to the latest version to get it. But when you are not an expert in rooting your device and prefer not to update your Android OS, try to install apps that are compatible with your device.
• Speaking of compatibility, most of the Android devices are now only support specific format called APK. So you are ploughing the sand by trying to install .jar or any other files on your Android phone.
• If you're getting an error message stating "insufficient storage available" when installing an app on your Android smartphone or tablet, you are going to need to delete something off your device's internal storage. In your device, press Settings > Storage > Phone Storage (or could be Internal storage) > apps> Click Clear cache and speed up your Android phone. This will give you some space to download your desired app.
• Lots of people now use screen dimming applications to modify the brightness of handsets in the evening. Such applications work by overlaying the whole screen with a translucent window, and letting touch events pass through to the activity below. As a result, you may get an unresponsive Install button. Simply disable screen dimming app before installation and problem solved.
