需要您的幫助！Android應用程序崩潰 - 無法實例化活動ComponentInfo
我是Android新手，由於某種原因，我的應用停止工作，並在啓動時崩潰。
我不確定它是否相關，但我已經將Maven添加到項目中。 這裏的錯誤日誌：

這裏的清單：

android:versionName="1.0" >

</intent-filter>
</activity>
<activity

android:label="@string/title_activity_main_menu" >

</application>
和這裏的活動：
public class SplashActivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
Thread StartTimer = new Thread(){
public void run(){
try {
sleep(2000);
Intent main = new Intent(SplashActivity.this, MainActivity.class);
startActivity(main);
finish(); //kills the current activity
}
catch (InterruptedException ex){}
}
};
StartTimer.start();
}
}
下面是pom.xml中

也這裏是第四Ë構建路徑設置：
導演結構：
請提供打包的apk的Maven構建腳本。 –
嗨馬庫斯，我可以在哪裏找到它？ – Gil404
在您的AndroidManifest.xml中嘗試'.SplashActivity'而不是'com.test.activities.SplashActivity' –
