DeployGate SDK functions are automatically disabled in the release builds. It will not work in the release builds unless you turn it on explicitly.
There are two solutions to this problem:
Use a debug build
Using code: DeployGate.install(this, null, true). The last 'true' parameter will make the DeployGate SDK available in the release builds.
As for Android 4.1 or higher, add android.permission.READ_LOGS to your AndroidManifest.xml to collect the remote Logcat logs.
