Question

Chooser Intent正在AVD工作，但没有在真正的手机上工作。我的手机是samsumg galaxy core。我将我的应用程序发送到我的电子邮件并下载到手机中并安装完毕。该应用程序正在真正的手机中工作，但只有选择器的Intent部分无效。在选择器意图下，我有3个意图用于从相机拍摄照片，另一个用于从图库中选择图片，另一个用于从视图中移除所选图片。它在Chooser中显示消息“无法找到执行此操作的应用程序”。我的代码如下。

请注意，这适用于AVD（模拟器）但不适用于真实手机。可能是什么问题？

    ImageButton imagebutton = (ImageButton) findViewById(R.id.profile_picture);
    imagebutton.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub


            Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

            Intent galleryIntent = new Intent(Intent.ACTION_GET_CONTENT,null);
            galleryIntent.setType("image/*");
            galleryIntent.addCategory(Intent.CATEGORY_OPENABLE);

            Intent removeProfPic = new Intent();

            String mPackage ="com.example.myapp";
            String mClass = mPackage + "." + "RemoveProfilePic";

            removeProfPic.setComponent(new ComponentName(mPackage, mClass));

            Intent[] intentArray =  {cameraIntent,galleryIntent};

            Intent chooser = new Intent(Intent.ACTION_CHOOSER);
            chooser.putExtra(Intent.EXTRA_TITLE, "Choose");
            chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);

            chooser.putExtra(Intent.EXTRA_INTENT, removeProfPic);

            startActivityForResult(chooser,1);

        }

    });

：：

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (resultCode != RESULT_CANCELED && data != null)
    {
        if (requestCode == 1 && resultCode == RESULT_OK)
        {
            Uri pic_uri = data.getData();

            if(pic_uri !=null)
            {
                try 
                {
                    Bitmap picture = MediaStore.Images.Media.getBitmap(this.getContentResolver(), pic_uri);

                    ImageButton imagebtn = (ImageButton) findViewById(R.id.profile_picture);
                    imagebtn.setImageBitmap(picture);
                    profilePictureSet = true;
                }

                catch (Exception e) 
                {
                    e.printStackTrace();
                }
            } 

            else 
            {
                Bundle b = data.getExtras();
                String s = b.getString("key1");

                if (s.equals("delete"))
                {
                    ImageButton imagebtn = (ImageButton) findViewById(R.id.profile_picture);
                    imagebtn.setImageResource(R.drawable.default_img);
                    profilePictureSet = false;

                }
                else
                {
                    Bitmap bitmap=(Bitmap) data.getExtras().get("data");

                    ImageButton imagebtn = (ImageButton) findViewById(R.id.profile_picture);
                    imagebtn.setImageBitmap(bitmap);
                    profilePictureSet = true;
                }
            }

            super.onActivityResult(requestCode, resultCode, data);
        }
    }
}

我也尝试在Androidmanifest.xml中包含以下内容

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.hardware.camera" />
<uses-permission android:name="android.hardware.camera.autofocus" />

但仍然无法工作..感谢任何帮助..提前致谢！

我刚刚交换了galleryIntent和removeProfPic，如下所示，现在正在使用它。谢谢！

        :
        Intent[] intentArray =  {cameraIntent,removeProfPic};
        :
        :
        chooser.putExtra(Intent.EXTRA_INTENT, galleryIntent);
        :

您没有为ex ...

设置意图数据类型

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { "some@email.address" });
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(intent, "Send To"));

Android Chooser Intent在AVD中工作但不在真实设备中/无法找到执行此操作的应用程序
