How to Restart Android App Programmatically (ProcessPhoenix)

Sep 28, 2018

android

Restart the current android app (not just Activity, but the whole Application)

ProcessPhoenix.triggerRebirth(context);

Ensure AndroidManifest.xml has the entry <category android:name="android.intent.category.DEFAULT" />, else you might bump into the following exception

java.lang.IllegalStateException: Unable to determine default activity for com.luasoftware.luapass. Does an activity specify the DEFAULT category in its intent filter? at com.jakewharton.processphoenix.ProcessPhoenix.getRestartIntent(ProcessPhoenix.java:89)

<manifest ...>
    <application ...>
        <activity
            android:name=".view.LoginActivity"
            android:theme="@style/AppTheme.NoActionBar"
            android:windowSoftInputMode="adjustPan">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

                <!-- for Pheonix -->
                <category android:name="android.intent.category.DEFAULT" />
            </intent-filter>
        </activity>
    </application>
</manifest>
