WAKEUP!

How many times a day do you push code to your phone and then pick it up, press the power button to wake the device and then swipe to unlock? If you're like me that answer is probably hundreds!

By adding a couple of permissions to your src/debug/AndroidManifest.xml file and adding a helper class in src/debug/... that can be called from your activities, you can wakeup and unlock the device automatically when you push code to your phone.

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- Add this as a debug manifest so the permissions won't be required by your production app -->
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.DISABLE_KEYGUARD" />
</manifest>

BaseActivity.java

public class BaseActivity extends Activity {

    @Override
    protected void onStart() {
        super.onStart();
        // Wake the device and show our activity
        if (BuildConfig.DEBUG) {
            // Calling this from your launcher activity is enough, but I needed a good example spot ;)
            DebugUtils.riseAndShine(this);
        }
    }
}
