Question

I am trying to make a second page show up via a BroadcastReceiver, but the App keeps crashing and I don’t know why.
This might be a problem of the correct context.

public class ScreenReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

        if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
            Log.v("$$$$$", "In Method: ACTION_SCREEN_OFF");

        } else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
                    Log.v("$$$$$", "In Method: ACTION_SCREEN_ON");
            changeActivity(context);
        } else if (intent.getAction().equals(Intent.ACTION_USER_PRESENT)) {
                    Log.v("$$$$$", "In Method: USER_PRESENT");
        }
    }

public void changeActivity(Context context) {

    Intent intent = new Intent(context, Second_Page.class);

    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);

    context.startActivity(intent);
    }
}

My Manifest. In there I declare the class that the log file states is missing:

    <uses-sdk android:minSdkVersion="14" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name=".CatchUnlockActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="second_page" >
        </activity>
    </application>

</manifest>

Found the solution:
The declaration of the classes is case-sensitive!

Changed every occurrence from “second_page” to “Second_Page” and now it works.
