Android RuntimePermissions运行时权限：批量权限申请

绝大多数情况一个APP不可能只有单个权限，往往需要运行时批量申请n多个权限。比如在Androidmanifest里面写了两个权限：

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

那么在运行时申请权限，要点是把全部权限装入到一个String数据里面，批量做一次申请：

package zhangphil.permission;import android.Manifest;import android.os.Build;import android.support.v4.app.ActivityCompat;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;public class MainActivity extends AppCompatActivity {    private final String TAG = "ZHANG PHIL";    private final int PERMISSION_REQUEST = 0xa00;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {            ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}, PERMISSION_REQUEST);        }    }    @Override    public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {        switch (requestCode) {            case PERMISSION_REQUEST:                if (grantResults != null && permissions != null) {                    for (int i = 0; i < grantResults.length; i++) {                        Log.d(TAG, "grantResults[" + i + "]:" + grantResults[i]);                        Log.d(TAG, "permissions[" + i + "]:" + permissions[i]);                    }                }                break;        }    }}

代码运行结果logcat输出：
