我在 Play 商店中上传了一个应用程序，我收到了几条评论说它有病毒，有时它会强制手机自行重启。我的应用程序中的代码非常简单：只有一个活动有多个位置，您可以听到它们或将它们设置为铃声。你能给我什么建议吗？
我的应用程序代码：
b1_2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
if(saveas(soundid,save_name)){
Toast.makeText(Main.this, "The sound was set as ringtone!",
Toast.LENGTH_LONG).show();
};
}
});
public boolean saveas(int ressound,String filename){
byte[] buffer=null;
InputStream fIn = getBaseContext().getResources().openRawResource(ressound);
int size=0;
try {
size = fIn.available();
buffer = new byte[size];
fIn.read(buffer);
fIn.close();
} catch (IOException e) {
// TODO Auto-generated catch block
return false;
}
String path="/sdcard/media/ringtones/";
boolean exists = (new File(path)).exists();
if (!exists){new File(path).mkdirs();}
FileOutputStream save;
try {
save = new FileOutputStream(path+filename);
save.write(buffer);
save.flush();
save.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
return false;
} catch (IOException e) {
// TODO Auto-generated catch block
return false;
}
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,
Uri.parse("file://"+path+filename)));
File k = new File(path, filename);
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "clip_"+save_name);
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
values.put(MediaStore.Audio.Media.ARTIST, "clip");
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
values.put(MediaStore.Audio.Media.IS_ALARM, true);
values.put(MediaStore.Audio.Media.IS_MUSIC, true);
//Insert it into the database
Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());
getContentResolver().delete(uri, MediaStore.MediaColumns.DATA + "=\"" +
k.getAbsolutePath() + "\"", null);
Uri newUri= this.getContentResolver().insert(uri, values);
RingtoneManager.setActualDefaultRingtoneUri(
this, RingtoneManager.TYPE_RINGTONE, newUri);
return true;
}
所需的权限是：
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_SETTINGS"></uses-permission>
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
它可以在没有互联网的情况下工作，但我只有一个直接链接到我在 google play 商店中的开发人员页面，为了避免崩溃，我使用了这个功能：
(if link is pressed)
if (isOnline()){
open page
} else {
do nothing
}
public boolean isOnline() {
boolean connectedWifi = false;
boolean connectedMobile = false;
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo[] networks = cm.getAllNetworkInfo();
for (NetworkInfo ni : networks) {
if ("WIFI".equalsIgnoreCase(ni.getTypeName()))
if (ni.isConnected())
connectedWifi = true;
if ("MOBILE".equalsIgnoreCase(ni.getTypeName()))
if (ni.isConnected())
connectedMobile = true;
}
return connectedWifi || connectedMobile;
}
