**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：

09-25 11:10:17.354 14247-14247/zhangphil.permission D/ZHANG PHIL: grantResults[0]:0
    09-25 11:10:17.355 14247-14247/zhangphil.permission D/ZHANG PHIL: permissions[0]:android.permission.CAMERA
    09-25 11:10:17.355 14247-14247/zhangphil.permission D/ZHANG PHIL: grantResults[1]:0
    09-25 11:10:17.355 14247-14247/zhangphil.permission D/ZHANG PHIL: permissions[1]:android.permission.WRITE_EXTERNAL_STORAGE
