Question

我的应用程序基于向用户显示当前位置。所以在我的MainActivity.java中我放了一个locate按钮。但是当我运行应用程序并按下定位按钮时，我的应用就会停止。

我的Gps.java

if(status!=ConnectionResult.SUCCESS){ // Google Play Services are not available
    int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
dialog.show();
}else
{ 
    SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
googleMap = fm.getMap();
googleMap.setMyLocationEnabled(true);
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = locationManager.getBestProvider(criteria, true);
Location location = locationManager.getLastKnownLocation(provider);

       onLocationChanged(location);
}
locationManager.requestLocationUpdates(provider, 20000, 0, this);
}
sendBtn = (Button) findViewById(R.id.button1);
sendBtn.setOnClickListener(new View.OnClickListener()
{
 public void onClick(View view) {
    sendSMSMessage();
 }
});
}
@Override
public void onLocationChanged(Location location) {

double latitude = location.getLatitude();
double longitude = location.getLongitude();
LatLng latLng = new LatLng(latitude, longitude);
googleMap.moveCamera(CameraUpdateFactory.newLatLng(latLng));
tvLocation.setText("Latitude:" +latitude+ ", Longitude:"+longitude);

       smsManager.sendTextMessage(con1, null, "I am Out please call me!!", null, null);
       Toast.makeText(getApplicationContext(), "SMS sent.",
       Toast.LENGTH_LONG).show();
    } catch (Exception e) {
       Toast.makeText(getApplicationContext(),
       "SMS faild, please try again.",
       Toast.LENGTH_LONG).show();
       e.printStackTrace();
    }
}

@Override

@Override

在您的清单文件的<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />元素中附加<application>。

Answer 2

logcat正在说：

04-16 21:04:18.033: E/AndroidRuntime(18078): Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value.  Expected 7095000 but found 0.  You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

总是在logcat中看这个引起：，它应该向您显示足够的信息来查找和纠正您的应用程序的问题，就像在这种情况下一样。

    The meta-data tag in your app's AndroidManifest.xml does not have the right value.  
Expected 7095000 but found 0.  
You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

所以只要做它说的，把这个

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

在 AndroidManifest.xml 文件中的<application>标记内。

更新：

正如我所说的那样，你应该寻找引起的，这里是

04-17 20:15:36.956: E/AndroidRuntime(24437): 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:
04-17 20:15:36.956: E/AndroidRuntime(24437): <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

见：

The Maps API requires the additional following permissions to be set in the AndroidManifest.xml to ensure a correct behavior:<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

现在只需将该权限添加到AndroidManifest：

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

Answer 3

从

中更改Fragment代码

android:name="com.google.android.gms.maps.MapFragment"

到

android:name="com.google.android.gms.maps.SupportMapFragment"

如果这不能解决，那么

在应用程序元素中添加元数据：Logcat清楚地显示错误。

04-16 21:04:18.033: E/AndroidRuntime(18078): Caused by: java.lang.IllegalStateException: The meta-data tag in your app's AndroidManifest.xml does not have the right value.  Expected 7095000 but found 0.  You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />

喜欢这个：

<application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
            ...
