java - Activity 启动时应用程序崩溃

Question

我正在创建一个应用程序，单击按钮时必须在其中显示 map 。但是，当单击 map 按钮而不是显示 map 时，应用程序崩溃，并显示“不幸的是，‘应用程序’已停止”，这是我的代码:

java文件:

package com.example.jamaattiming;

import android.os.Bundle;
import android.app.Activity;
//import android.app.FragmentTransaction;
import android.view.Menu;
import com.example.jamaat_times.R;
import com.google.android.gms.maps.GoogleMap;
//import com.google.android.gms.maps.MapFragment;

public class TagYourself extends Activity {

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

        /* MapFragment mMapFragment = MapFragment.newInstance();
         FragmentTransaction fragmentTransaction =
                 getFragmentManager().beginTransaction();
         fragmentTransaction.add(R.id.map, mMapFragment);
         fragmentTransaction.commit();

         GoogleMap maps;
         maps=(((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap());*/


    }

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

}

这是 xml 文件:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

        android:layout_width="match_parent"

</RelativeLayout>

Answer 1

看一下 logcat 的这一行:

 Caused by:
java.lang.SecurityException: The Maps API requires the additional following permissions to be set in the AndroidManifest.xml to ensure a correct behavior: 04-01 00:32:39.709: 
E/AndroidRuntime(18546): <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 04-01 00:32:39.709: E/AndroidRuntime(18546):   at maps.e.ci.a(Unknown Source)

您似乎忘记添加权限:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

到您的 AndroidManifest xml 文件
