Android share按钮音频来自原始

Question

我的Android项目中的raw文件夹中有各种音频文件。我的代码不起作用。当我单击共享按钮应用程序时，它崩溃了。

这是我的代码：

public void onClick(View v) {
    InputStream inputStream;
    FileOutputStream fileOutputStream;
    try {
        inputStream = getResources().openRawResource(R.raw.numer_1);
        fileOutputStream = new FileOutputStream(
            new File(Environment.getExternalStorageDirectory(), "sound.mp3"));

        byte[] buffer = new byte[1024];
        int length;
        while ((length = inputStream.read(buffer)) > 0) {
            fileOutputStream.write(buffer, 0, length);
        }
        inputStream.close();
        fileOutputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
    Intent intent = new Intent(Intent.ACTION_SEND);
    intent.putExtra(Intent.EXTRA_STREAM,
    Uri.parse("file://" + Environment.getExternalStorageDirectory() + "/sound.mp3" ));
    intent.setType("audio/*");
    startActivity(Intent.createChooser(intent, "Share sound"));
}

和Android清单添加：

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

Answer 1

if you use this your app will not crash again. The problem is at **Environment.getExternalStorageDirectory()**you're missing **.getPath()**

使用以下代码作为您意图的指南。

final Intent audIntent = new Intent(android.content.Intent.ACTION_SEND);
                                     String audioName="kidi.mp3";
                                     audIntent.setType("audio/mp3");
                                     audIntent.putExtra(android.content.Intent.EXTRA_STREAM, Uri.parse("file://"+"/Environment.getExternalStorageDirectory().getPath()/"+audioName));
                                     startActivity(Intent.createChooser(audIntent, "Share Audio "));
