android - 检查正确的Google Play服务可用: “Unfortunately application has stopped working”

每次我在手机上运行应用程序时都会崩溃。有什么不对？它说不幸的是“appname”已经停止工作。我还尝试了其他方法来检查googleplay服务，但它总是崩溃。我更新了Google Play服务，并且可以正常使用的Google Map v2正常运行。此代码有解决方案吗？它在运行android 4.1.2的手机和AVD上崩溃。

package com.example.checkgoogleplayproject;

import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.Menu;
import android.widget.TextView;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;

public class MainActivity extends Activity {

    @Override
    protected void onResume() {
        super.onResume();

        // Getting reference to TextView to show the status
        TextView tvStatus = (TextView)findViewById(R.id.tv_status);

        // Getting status
        int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());

        // Showing status
        if(status==ConnectionResult.SUCCESS)
            tvStatus.setText("Google Play Services are available");
        else{
            tvStatus.setText("Google Play Services are not available");
            int requestCode = 10;
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
            dialog.show();
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
}

最佳答案

要检查GooglePlayServices是否可用，请使用 GoogleApiAvailability 。 isGooglePlayServicesAvailable() ，与 GooglePlayServicesUtil 相同。 isGooglePlayServicesAvailable() 不推荐使用的。

public boolean isGooglePlayServicesAvailable(Context context){
    GoogleApiAvailability googleApiAvailability = GoogleApiAvailability.getInstance();
    int resultCode = googleApiAvailability.isGooglePlayServicesAvailable(context);
    return resultCode == ConnectionResult.SUCCESS;
}

更新:检查google play服务是否可用，如果google play服务不可用并且错误可恢复，则打开对话框以解决错误。

public boolean isGooglePlayServicesAvailable(Activity activity) {
    GoogleApiAvailability googleApiAvailability = GoogleApiAvailability.getInstance();
    int status = googleApiAvailability.isGooglePlayServicesAvailable(activity);
    if(status != ConnectionResult.SUCCESS) {
        if(googleApiAvailability.isUserResolvableError(status)) {
              googleApiAvailability.getErrorDialog(activity, status, 2404).show();
        }
        return false;
    }
    return true;
}
