将缓存图像设置为联系人照片

Question

我想将图像设置为联系人图标.该图像存储在缓存中.这是我的代码 -

Intent myIntent = new Intent();
    myIntent.setAction(Intent.ACTION_ATTACH_DATA);
    myIntent.setType("image/jpeg");
    myIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(getApplicationContext().getCacheDir()
            .getAbsolutePath()
            + "/" + fileName));
   startActivityForResult(Intent.createChooser(myIntent, "Set As"),
            200);

这段代码给了我选项 - 联系人图标,壁纸.当我选择联系人图标时,联系人列表正在打开.当我从联系人列表中选择任何联系人时,该应用程序正在崩溃.

日志是 -

我找不到我的代码有什么问题.我需要为此添加一些权限吗？

这可以是android设置图像的副本作为联系人图标/壁纸

但我没有找到任何解决方案.如果有人知道解决方案,请帮助我.

我已经做了.你只需要设置正确的意图,意图是

Uri sendUri = Uri.fromFile(externalFile)
Intent intent = new Intent(Intent.ACTION_ATTACH_DATA);
        intent.setDataAndType(sendUri, "image/jpg");
        intent.putExtra("mimeType", "image/jpg");
        startActivityForResult(Intent.createChooser(intent, "Set As"), 200);
