Android6.0动态申请权限（简单实用）

简单代码：

public class LaunchActivity extends AppCompatActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_launch);
        if (isGrantSDCardReadPermission()) {
           //
        } else {
            requestPermission();
        }
    }

    private boolean isGrantSDCardReadPermission() {
        return PermissionUtils.isGrantSDCardReadPermission(this);
    }

    private void requestPermission() {
        PermissionUtils.requestSDCardReadPermission(this, REQUEST_CODE_SDCARD_READ);
    }

    private static final int REQUEST_CODE_SDCARD_READ = 1;

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        switch (requestCode) {
            case REQUEST_CODE_SDCARD_READ:
                if (isGrantSDCardReadPermission()) {
                    //
                } else {
                    Toast.makeText(this, "failure because without sd card read permission", Toast.LENGTH_SHORT).show();
                }
                break;

            default:
                break;
        }
    }

}

public class PermissionUtils {
    /**
     * 是否有权限
     *
     * @param context
     * @return
     */
    public static boolean checkSelfPermission(Context context, String permission) {
        if (null == context) {
            return false;
        }
        int per = ContextCompat.checkSelfPermission(context, permission);
        return per == PackageManager.PERMISSION_GRANTED;
    }

    /**
     * Check that all given permissions have been granted by verifying that each entry in the
     * given array is of the value {@link PackageManager#PERMISSION_GRANTED}.
     *
     * @see Activity#onRequestPermissionsResult(int, String[], int[])
     */
    public static boolean verifyPermissions(int[] grantResults) {
        // At least one result must be checked.
        if (null == grantResults || grantResults.length < 1) {
            return false;
        }

        // Verify that each required permission has been granted, otherwise return false.
        for (int result : grantResults) {
            if (result != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
        return true;
    }

    public static boolean isGrantSDCardReadPermission(Context context) {
        return checkSelfPermission(context, Manifest.permission.READ_EXTERNAL_STORAGE);
    }

    public static void requestSDCardReadPermission(Activity activity, int requestCode) {
        ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, requestCode);
    }
}

最后再附上需要动态申请的权限组，每组只要有一个权限申请成功，就默认组内其他权限申请成功了。

    permission:android.permission.WRITE_CONTACTS
    permission:android.permission.GET_ACCOUNTS
