android - 获取默认图片开启器的包名

Question

我有一个问题。在不同的手机上运行我的测试时，在尝试打开图库时，它不起作用。

现在，我想要做的是获取默认图库开启器应用程序的包名称，以便我可以在我的代码中使用它。我如何以编程方式执行此操作？

这是我在 Nexus 5 上运行测试时的使用方式。

Resources resources = InstrumentationRegistry.getTargetContext().getResources();
        Uri imageUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" +
                resources.getResourcePackageName(R.drawable.ic_launcher) + '/' +
                resources.getResourceTypeName(R.drawable.ic_launcher) + '/' +
                resources.getResourceEntryName(R.drawable.ic_launcher));
        Intent resultData = new Intent();
        resultData.setData(imageUri);
        Instrumentation.ActivityResult result = new Instrumentation.ActivityResult(Activity.RESULT_OK, resultData);
        intending(toPackage("com.google.android.apps.photos")).respondWith(result);
        //Click the select button
        onView(withId(R.id.register_image)).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        onView(withText("From Gallery")).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        Spoon.screenshot(getActivityInstance(), "picture_selected");

基本上，我需要做的就是获取图像应用程序的包名。

所以，你会想做这样的事情:

创建 utils 类并添加以下方法:

 public static String getPackageForGalery() {
            Intent mainIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            mainIntent.setType("image/*");
            List<ResolveInfo> pkgAppsList = getApplicationContext().getPackageManager().queryIntentActivities(mainIntent, PackageManager.GET_RESOLVED_FILTER);
            int size = pkgAppsList.size();
            for (ResolveInfo infos : pkgAppsList) {
                return infos.activityInfo.processName;

            }
            return null;
        }

现在，在您的代码中，执行以下操作:

Resources resources = InstrumentationRegistry.getTargetContext().getResources();
        Uri imageUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://" +
                resources.getResourcePackageName(R.drawable.ic_launcher) + '/' +
                resources.getResourceTypeName(R.drawable.ic_launcher) + '/' +
                resources.getResourceEntryName(R.drawable.ic_launcher));
        Intent resultData = new Intent();
        resultData.setData(imageUri);
        Instrumentation.ActivityResult result = new Instrumentation.ActivityResult(Activity.RESULT_OK, resultData);
        intending(toPackage(YourUtilsClass.getPackageForGalery())).respondWith(result);
        //Click the select button
        onView(withId(R.id.register_image)).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        onView(withText("From Gallery")).perform(click());
        threadSleep(MILISECONDS_TIMEOUT);
        Spoon.screenshot(getActivityInstance(), "picture_selected");
