AndroidMainfest.xml
-------------------
<activity android:name=".main.Activity1"
android:configChanges="keyboard|keyboardHidden|orientation"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:launchMode="singleInstance" <= 此行絕對不能加,會造成呼叫其他的app
> <!-- Prevents authorization dialog from closing when screen orientation is changed -->
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
-------------------
可用BroadcastReceiver來收到廣播,再行處理,此方法每次呼叫 不會onCreate其activity
Intent intent = new Intent();
intent.setComponent(new ComponentName("com.captain.voice.alexa.mobile",
"com.captain.voice.alexa.mobile.main.Audio_Record"));
intent.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(intent);
