java - Can't play the recorded file -
i'm making app records audio long imagebutton touched , held. achieved following code:
public class mainactivity extends activity { mediarecorder recorder; mediaplayer mediaplayer; //storage paths string storagepath; string externalstoragepath; //full output paths string externaloutputpath; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); //audio recorder recorder = new mediarecorder(); recorder.reset(); recorder.setaudiosource(mediarecorder.audiosource.mic); recorder.setoutputformat(mediarecorder.outputformat.three_gpp); recorder.setaudioencoder(mediarecorder.audioencoder.amr_nb); if (environment.getexternalstoragestate().equals(environment.media_mounted)) { externalstoragepath = environment.getexternalstoragedirectory().getabsolutepath(); externaloutputpath = externalstoragepath + file.separator + "/android/data/com.whizzappseasyvoicenotepad/test.mp3"; recorder.setoutputfile(externaloutputpath); } else { storagepath = environment.getdatadirectory().getabsolutepath(); recorder.setoutputfile(storagepath + "/android/data/com.whizzappseasyvoicenotepad/test.mp3"); } //image button ontouchlistener final imagebutton recbtn = (imagebutton) findviewbyid(r.id.recbutton); recbtn.setontouchlistener(new ontouchlistener(){ @override public boolean ontouch(view v, motionevent event) { if (event.getaction() == motionevent.action_down) { recbtn.setimageresource(r.drawable.record_btn_pressed); try { recorder.prepare(); recorder.start(); } catch (illegalstateexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } } else if (event.getaction() == motionevent.action_up) { recbtn.setimageresource(r.drawable.record_btn); try { recorder.prepare(); recorder.stop(); recorder.reset(); recorder.release(); recorder = null; } catch (illegalstateexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } log.i(storage_service, "file saved to: " + externalstoragepath + "/android/data/com.whizzappseasyvoicenotepad/test.3gp"); } return true; } }); } //end of oncreate now after i've stopped recording, searched mp3 file in file manager (android app) , tried playing music player doesn't work. says file can't played.
i tried add "test play" button app, try , play recorded file mediaplayer doesn't work either. press play button, app crashes.
public void testplay (view v) throws illegalargumentexception, securityexception, illegalstateexception, ioexception{ mediaplayer = new mediaplayer(); mediaplayer.setdatasource(externaloutputpath); mediaplayer.start(); } yes, did add android:onclick="testplay" xml file
