android6.0权限问题

4000

之前学baidu 地图的代码，有6.0sdk 发现无法定位成功。

后来发现是 6.0的权限问题。

普通权限：只需要在androidmanifest.xml中声明相应的权限，在安装应用时，会默认获得许可。

需要申请的权限：例如：打开gps 定位
 

倒包：

import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;

代码：

final private int REQUEST_CODE_ASK_PERMISSIONS = 123;

private void insertDummyContactWrapper() {
int hasWriteContactsPermission = ContextCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION);
if (hasWriteContactsPermission != PackageManager.PERMISSION_GRANTED) {
//TODO
if (!ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.ACCESS_FINE_LOCATION)) {
showMessageOKCancel("You need to allow access to Contacts",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
ActivityCompat.requestPermissions(MainActivity.this,new String[] {Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_CODE_ASK_PERMISSIONS);
}
});
return;
}
ActivityCompat.requestPermissions(MainActivity.this,new String[] {Manifest.permission.ACCESS_FINE_LOCATION},
REQUEST_CODE_ASK_PERMISSIONS);
return;
//TODO
}
}

private void showMessageOKCancel(String message, DialogInterface.OnClickListener okListener) {
new AlertDialog.Builder(MainActivity.this)
.setMessage(message)
.setPositiveButton("OK", okListener)
.setNegativeButton("Cancel", null)
.create()
.show();
}

}
