Android 动态权限

<!--以照相机为例--><uses-permission android:name="android.permission.CAMERA" />

//检查权限private void check() {    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {        int permission = ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA);        if (permission != PackageManager.PERMISSION_GRANTED) {            requestPermissions(new String[]{Manifest.permission.CAMERA}, yourCode);        } else {            go();        }    } else {        go();    }}//权限回调@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {    super.onRequestPermissionsResult(requestCode, permissions, grantResults);    if (requestCode == yourCode) {        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {            go();        } else {            //未被授权        }    }}//授权后执行private void go() {}
