共享未经WRITE_EXTERNAL_STORAGE许可的应用程序屏幕截图？

Question

Is it possible to share own app screenshots without adding any permissions ?

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

And this is my others apps code which is works on copy to cache and share

public void sendFile(File paramFile) {

        String fileExtension = ".apk";
        File temporaryFile;
        try {
            temporaryFile = File.createTempFile(paramFile.getName(), fileExtension, getApplicationContext().getExternalCacheDir());
            copy(paramFile, temporaryFile);
        } catch (Exception e) {
            temporaryFile = paramFile;
        }
        Intent localIntent = new Intent();
        localIntent.setAction("android.intent.action.SEND");
        localIntent.putExtra("android.intent.extra.STREAM", Uri.fromFile(temporaryFile));
        localIntent.setType("application/*");
        localIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        startActivity(Intent.createChooser(localIntent, ""));
    }

Answer 1

Save your image to internal storage (eg, getCacheDir() ), then use FileProvider to make it available to other apps. See the documentation for more.

Answer 2

You are using getExternalCacheDir()

it absolute the path to youraplication specific directory on the primary external storage device where the application can place cache files it owns. These files are internal to the application, and not typically visible to the user as media.

There is no security enforced with these files. no need to add the permissions to read or write to the returned path. it's always accessible to the youraplication app. This only applies to paths generated for package name of the youraplication.

android.Manifest.permission.WRITE_EXTERNAL_STORAGE 
android.Manifest.permission.READ_EXTERNAL_STORAGE
