无法传递结果-无法执行非无效方法openCamera [英] Failure delivering result - Cannot execute non-void method openCamera

问题描述

我正在使用Google的 EasyPermissions 库来处理Android 6上的权限.捕获图像的按钮，它要求我授予CAMERA和WRITE_EXTERNAL_STORAGE的权限.

I'm using EasyPermissions library from Google to handle Permissions on Android 6. The first time I click the button to capture image it asks me to give permissions for CAMERA and for WRITE_EXTERNAL_STORAGE.

在我接受了两个权限的应用程序崩溃后，出现错误消息，您可以在下面看到:

After I have accepted both permissions app crashes with the error message you can see below :

和openCamera()方法:

@Override
@AfterPermissionGranted(RC_CAMERA_PERM)
public void openCamera(int option) {
    if (EasyPermissions.hasPermissions(this, Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
        // Have permission, do the thing!
        Log.i(TAG, "openCamera Has Permissions ");

        Intent intent;

        switch (option) {
            case RECORD_VIDEO :
                intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
                intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, FIVE_MINS_IN_SECS);
                startActivityForResult(intent, RECORD_VIDEO);
                break;
            case CAPTURE_IMAGE :
                ContentValues values = new ContentValues();
                values.put(MediaStore.Images.Media.TITLE, "Image File name");
                mCapturedImageURI = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

                intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                intent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
                startActivityForResult(intent, CAPTURE_IMAGE);
                break;
            default:
                Log.i(TAG, "openCamera wrong option ");
                break;
        }

    } else {
        // Ask for Camera permission
        EasyPermissions.requestPermissions(this, getString(R.string.ask_camera_permission),
                RC_CAMERA_PERM, Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE);
    }
}

推荐答案

您会收到该异常，因为EasyPermission无法调用方法openCamera，因为它具有参数option.用AfterPermissionGranted注释的方法必须为空，以便EasyPermission可以调用它们.

You get that exception because EasyPermission can't invoke your method openCamera since it has the parameter option. The methods annotated with AfterPermissionGranted must be void so EasyPermission can invoke them.

此条件已在

要解决此问题，必须从方法openCamera中删除所有参数.

To resolve the issue you must remove any parameter from the method openCamera.
