android - GCM : why my application crash in GCMRegistrar. 检查设备(这个)；

Question

我有一个只有几行的简单应用程序，因为我试图找出为什么我的真实应用程序在 GCMRegistrar.checkDevice(this) 中崩溃(如果我删除它，我的应用程序不会崩溃)。谁能帮忙？ :(:

public class DemoActivity extends Activity {
private String TAG = "** pushAndroidActivity **";
private TextView mDisplay;
    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       GCMRegistrar.checkDevice(this);
       GCMRegistrar.checkManifest(this);
        setContentView(R.layout.main);
        mDisplay = (TextView) findViewById(R.id.display);
        mDisplay.setText("ciao");
}

list :

Answer 1

它可能在不支持 GCM 的设备上运行，因此您对 GCMRegistrar.checkDevice( this ); 的调用会引发异常。检查您的 logcat 以确定。

如果您在模拟器上对其进行测试，请确保您已将模拟器设置为使用 Google API。创建模拟器时，创建新 AVD 窗口有一个“目标”框。在显示“Google API”的框中选择内容。
