Question

我制作一个用于访问Camera的Android的AARplugins。但它不会激活onActivityResult。

public static void showCamera ( )     // Connect Camera
{
    String Uri;

    Activity CameraActivity = UnityPlayer.currentActivity;

    Toast.makeText(CameraActivity ,   "first"  ,Toast.LENGTH_LONG).show();
    Log.d(" before ImageUrl@@@@@@ ", "first");


CameraActivity.runOnUiThread(new Runnable()
{
    public void run() {
        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        CameraActivity.startActivityForResult(intent,1);
    }
});
}

///////////////不要激活↓///////////////////////// /////////

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)                           
{
    Log.d(" before ImageUrl@@@@@@ ", "twotwotwotwotwotwotwo"); //Don't activate
}

/////////////////////////////////////////////// /////////////////////////////

为什么不激活这个？

试试这个，

相机许可

    private static final int REQUEST_CAMERA = 112;


    btn_cam.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                  if (Build.VERSION.SDK_INT >= 23) {
                        String[] PERMISSIONS = {android.Manifest.permission.CAMERA};
                        if (!hasPermissions(mContext, PERMISSIONS)) {
                            ActivityCompat.requestPermissions((Activity) mContext, PERMISSIONS, REQUEST_CAMERAE );
                        } else {

                            //open camera
                        }
                    } else {

                        //open camera
                    }

                }
            });
        }

获取权限结果

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case REQUEST_CAMERA: {
                if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                   //open camera
                } 
            }
        }
    }

检查marshmallow的权限

    private static boolean hasPermissions(Context context, String... permissions) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
            for (String permission : permissions) {
                if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                    return false;
                }
            }
        }
        return true;
    }

的AndroidManifest.xml

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

[Unity 3D]我想访问Android Camera并选择路径
