+## Troubleshooting:
+
+### Application Not Installed
+
+Android might complain the application is not correctly installed. If so, check the following:
+
+* Check that the debug keystore is properly generated.
+* Check that jarsigner is from JDK6.
+
+If it still fails, open a command line and run logcat:
+
+C:\android-sdk\platform-tools> adb logcat
+
+And check the output while the application is installed. Reason for failure should be presented there. 
+Seek assistance if you can't figure it out.
+
+### Application Exits Immediately
+
+If the application runs but exits immediately, there might be one of the following reasons:
+
+* libgodot_android.so is not in libs/armeabi
+* Device does not support armv7 (try compiling yourself for armv6)
+* Device is Intel, and apk is compiled for ARM.
+
+In any case, "adb logcat" should also show the cause of the error.
