Question

代码：

    setContentView(R.layout.splashscreen);
    Thread timer = new Thread() {

        @Override
        public void run() {
            // TODO Auto-generated method stub

            try {
                sleep(5000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            } finally {
                intent=new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.google.com/"));
                startActivity(intent);
            }

        }

    };
    timer.start();
}



@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    this.finish();

}
  }

正如大家们所看到的，这是一个非常简单的程序，它会显示一个闪屏，然后会在浏览器中打开网址。这里的一切都很好。现在通过使用后退按钮我退出应用程序。但是当我尝试按下已安装的应用程序图标时，系统会立即向我致敬"app is not installed on your phone"。

当我检查正在运行的服务时，它始终在那里，我的logcat说："Launcher does not have permission to launch the intent"。

所以我的第一个问题：为什么我的应用程序一直在运行，虽然我在finish()方法中调用了onPause()？

Q2。这条logcat消息表示什么？

这是我的清单（猜测你认为我没有为互联网添加uses-permission但我有）：

 <?xml version="1.0" encoding="utf-8"?>
  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.abc.xyz.main"
    android:versionCode="1"
    android:versionName="1.0.1" >

<uses-sdk android:minSdkVersion="8" />
   <uses-permission android:name="android.permission.INTERNET"/>


<application
    android:icon="@drawable/app_icon"
    android:label="@string/app_name" android:permission="android.permission.INTERNET"  android:description="@string/appdescription">

        <activity
            android:name=".SplashActivity"
             android:label="@string/app_name"
              android:screenOrientation="portrait" >
            <intent-filter>
               <action android:name="android.intent.action.MAIN" />

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


   </application>

   </manifest>

以下是logcat：

Answer 1

如果你正在使用冰淇淋三明治，（我记得在SO中的某个地方阅读）不仅权限必须在自己的标签中，应用程序不能同时具有属性“android.permission.INTERNET”。所以只需从应用程序节点中删除它并尝试...

Answer 2

尝试删除：

android:permission="android.permission.INTERNET"

从这一部分：

<application
android:icon="@drawable/app_icon"
android:label="@string/app_name" android:permission="android.permission.INTERNET"  android:description="@string/appdescription">

但请将其留在清单的另一部分。
