with revoked permission android.permission.CAMERA

1,刚出现这样的问题我是直接把 CAMERA 移除掉

2.第一步判断时候授权。

if (Build.VERSION.SDK_INT >= 23) {
int checkCallPhonePermission = ContextCompat.checkSelfPermission(AppointmentDetailActivity.this, Manifest.permission.CAMERA);
 if(checkCallPhonePermission != PackageManager.PERMISSION_GRANTED){
 ActivityCompat.requestPermissions(AppointmentDetailActivity.this,new String[]{Manifest.permission.CAMERA},OPEN_CANMER);
 return;
 }else{
 showCamera();
 }
} else {
 showCamera();
}

第二步 接收返回的结果。

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case OPEN_CANMER:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
 showCamera();
 } else {
 Toast.makeText(AppointmentDetailActivity.this, "相机权限禁用了。请务必开启相机权", Toast.LENGTH_SHORT).show();
 }
break;
 default:
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
 }
}
