之前写过一篇如何在安卓APP中添加分享按钮?，这个也不是说没用，但是再上架Google Play Store 时被拒了（如下图所示），大意是赋予的读写权限过大以及不符合规范。

• AndroidManifest.xml权限添加

<!--    STORAGE PERMISSION FOR SCREEN SHOT-->
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

• 布局

...
<LinearLayout android:id="@+id/shared_preferences_container"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:background="#7E03A9F4">
    <TextView android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:textAlignment="center"
              android:layout_weight="10"
              android:text="@string/share_info"/>
    <Button android:id="@+id/share"
            android:background="@drawable/ic_share"
            android:layout_weight="1"
            android:layout_width="32dp"
            android:layout_height="32dp"
            android:layout_marginRight="10dp"/>
</LinearLayout>
...

• 主要引用

...
Button share = (Button) findViewById(R.id.share);
share.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Bitmap bitmap = takeScreenshot(gameWeb);
        try {
            saveImage(bitmap);
        } catch (IOException e) {
            e.printStackTrace();
        }
        shareIt(GameActivity.this);
    }
});
...

• 截图

public Bitmap takeScreenshot(View v) {
    View rootView = findViewById(android.R.id.content);
    Bitmap bitmap = Bitmap.createBitmap(rootView.getWidth(),rootView.getHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    rootView.draw(canvas);
    return bitmap;
}

• 存图

private void saveImage(Bitmap bitmap) throws IOException {
    Date dNow = new Date( );
    SimpleDateFormat ft = new SimpleDateFormat("yyyyMMddhhmmss");
    String name =  "HighTower_"+ft.format(dNow);
    OutputStream fos;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        ContentResolver resolver = getContentResolver();
        ContentValues contentValues = new ContentValues();
        contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, name);
        contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "image/jpeg");
        contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES);
        imageUri = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
        fos = resolver.openOutputStream(Objects.requireNonNull(imageUri));
    } else {
        String imagesDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).toString();
        File image = new File(imagesDir, name);
        fos = new FileOutputStream(image);
    }
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);
    Objects.requireNonNull(fos).close();
}

• 分享

private void shareIt (Context context){
    Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
    sharingIntent.setType("image/*");
    String shareBody = getString(R.string.shareBody);
    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getString(R.string.Score));
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
    sharingIntent.putExtra(Intent.EXTRA_STREAM,imageUri);
    startActivity(Intent.createChooser(sharingIntent, getString(R.string.share_via)));
}
