通过意图分享图片失败

Question

我正在尝试捕获图像，然后与应用程序共享。

private static final int CAMERA_REQUEST = 1888;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_result);
        Intent cameraIntent = new Intent(
               android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(cameraIntent, CAMERA_REQUEST);
        //start the camera and capture an image
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
        Uri imageUri = data.getData();
        //convert captured Image from Intent form to URI
        Intent shareIntent = new Intent();
        shareIntent.setAction(Intent.ACTION_SEND);
        shareIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
        shareIntent.setType("image/jpeg");
        startActivity(shareIntent);
        //share the image
    }
}

但是当我运行这段代码时，图像没有被共享。我的代码有bug吗?

有没有其他方法可以共享图像而不将其保存在内存中?

Answer 1

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri screenshotUri = Uri.parse("android.resource://com.android.test/*");
try {
    InputStream stream = getContentResolver().openInputStream(screenshotUri);
} catch (FileNotFoundException e) {
    e.printStackTrace();
}
sharingIntent.setType("image/jpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM, screenshotUri);
startActivity(Intent.createChooser(sharingIntent, "Share image using")); 

Answer 2

我要感谢Alexander帮我找到了解决方案。

下面是工作代码-

private static final int CAMERA_REQUEST = 1888;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_result);
        Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
        startActivityForResult(cameraIntent, CAMERA_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
        final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
               .putExtra(Intent.EXTRA_STREAM,
                Uri.parse(MediaStore.Images.Media.insertImage(getContentResolver(),
                        (Bitmap) data.getExtras().get("data"), "title", null)
               ))
               .setType("image/jpeg");
        startActivity(intent);
    }
}
