    setTitle(R.string.alert_title_success);

    ((Button)findViewById(R.id.button_share))
    .setOnClickListener(new View.OnClickListener() {

                Uri StringUri = Uri.fromFile(new File(sSongPath)); 
                Intent intent = new Intent(android.content.Intent.ACTION_SEND, StringUri);
                Intent in = new Intent(android.content.Intent.ACTION_SEND, StringUri, context, null);
                intent.setType("audio/*");

            }
        });
}

}

Answer 1

您的 Intent 是 Intent 不是 ishare Uri 是 stringUri 但您提到 ed 作为 StringUri .. 您可以发布整个代码 .. 以查看错误（如果有）

Answer 2

看到这个代码

@覆盖

protected void onCreate(Bundle savedInstanceState)

{

    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ((Button) findViewById(R.id.button_share))
            .setOnClickListener(new View.OnClickListener() {
                public void onClick(View view) {
                    Uri stringUri = Uri.fromFile(new File(""));
                    Intent sendIntent = new Intent();
        sendIntent.setAction(Intent.ACTION_SEND);// intent for sharing
        sendIntent.putExtra(Intent.EXTRA_TEXT, stringurl);
        sendIntent.setType("audio/*");
        sendIntent.putExtra(Intent.EXTRA_SUBJECT, StringTitle);
        startActivity(sendIntent);// getting error
                                                            // as create
                                                            // method
                                                            // startActivity(Intent)
                }
            });

}
