Android launching music player using intent
提问by shaneburgess
Is it possible to open the music app from my app in android, or is it best to write a whole new music app inside of mine. I would rather use theirs since the user will already be comfortable with it.
是否可以从我的 android 应用程序中打开音乐应用程序，或者最好在我的内部编写一个全新的音乐应用程序。我宁愿使用他们的，因为用户已经习惯了。

if (Build.VERSION.SDK_INT >= 24) {
try {
Method m = StrictMode.class.getMethod("disableDeathOnFileUriExposure");
m.invoke(null);
} catch (Exception e) {
e.printStackTrace();
}
}
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
File file = new File(YOUR_SONG_URI);
intent.setDataAndType(Uri.fromFile(file), "audio/*");

There are number of way by which you can achieve default audio player but those are device and OS specific.
您可以通过多种方式实现默认音频播放器，但这些都是特定于设备和操作系统的。

使用此代码片段，您可以获得默认的音频播放器。
try
{
Intent myIntent = new Intent(android.content.Intent.ACTION_VIEW);
File file = new File("audiofilepath");
String extension = android.webkit.MimeTypeMap.getFileExtensionFromUrl(Uri.fromFile(file).toString());
String mimetype = android.webkit.MimeTypeMap.getSingleton().getMimeTypeFromExtension(extension);
myIntent.setDataAndType(Uri.fromFile(file),mimetype);
startActivity(myIntent);
}
catch (Exception e)
{
e.printStackTrace();
}

This works for older versions and you May get FileUriExposed Exceptiondue to the security Update in the latest Versions. To avoid that use the following code
这适用于旧版本，由于最新版本中的安全更新，您可能会收到FileUriExposed 异常。为避免这种情况，请使用以下代码
try{
File file = new File(filepath);
String mimeType = "audio/*";
Uri fileURI = FileProvider.getUriForFile(
getApplicationContext(),
getApplicationContext()
.getPackageName() + ".provider", file);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(fileURI, mimeType);
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(intent);
}catch (Exception e){
Log.e(TAG,"-------------------------------------------------------FAILED TO PLAY SONG "+e);
}
Add the Following in AndroidManifest.xml
在AndroidManifest.xml 中添加以下内容
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
Create a file provider_paths.xmlunder res/xml/
在res/xml/下创建一个文件provider_paths.xml
<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="external_files"
path="."/>
</paths>
