How set to show the name of music and it on my phone

I have a question now i try create a music app on my phone. now I can see my file song But the name shown in the app is the file address instead. and if i want to play the file music in this app. What code do I need to add for get the name of music and play it on my phone? thank a lot
#Override
public void onClick(View view) {
mp.pause();
play.setEnabled(true);
stop.setEnabled(true);
pause.setEnabled(false);
}
});
stop.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (mp != null) {
mp.stop();
try {
mp.prepare();
} catch (IOException e) {
e.printStackTrace();
}
//mp.release()
play.setEnabled(true);
play.setEnabled(true);
stop.setEnabled(false);
}
}
});
send.setOnClickListener(new View.OnClickListener() {
//List<Intent> intentShareList = new ArrayList<Intent>();
#Override
public void onClick( View view ) {
msgs = msg.getText().toString();
System.out.print("msgs " + msgs);
// make line message
Log.d(TAG, "Txt " + msgs);
Intent shareIntent = new Intent();
String userId = "";
String sendText = "line://ti/p/~" + userId;
//shareIntent = null;
try {
shareIntent = Intent.parseUri(sendText,
Intent.URI_INTENT_SCHEME);
} catch (URISyntaxException e) {
e.printStackTrace();
}
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
shareIntent.putExtra(Intent.EXTRA_TEXT,msgs);
shareIntent.setType("text/plain");
startActivity(shareIntent);
}
});
}
AND
public class Songs {
//private
private String songTitle;
private String songAddress;
public Songs(String title){
//songID = id;
songTitle = title;
}
/*public long getSongID(){
return songId;
*/
public String getSongTitle(){
return songTitle;
}
}

now I can see my file song But the name shown in the app is the file
address instead
I think you are referring to the "Path" of the file, for example:
/storage/emulated/0/song.mp3 (Unix style path)
C:\Songs\song.mp3 (Window style path)
If you would like to parse (find out) the name of the file, use the following code:
String filePath = "/storage/emulated/0/song.mp3";
File f = new File(filePath);
String fileName = f.getName();
// fileName == "song.mp3"
In your case:
public class Songs {
private String title; // renamed from "songTitle"
private String path; // renamed from "songAddress"
private String fileName; // the file name of the song
public Songs(String title, String path){
this.title = title;
this.path = path;
File file = new File(path);
String fileName = f.getName();
this.fileName = fileName;
}
public String getTitle(){
return title;
}
public String getPath(){
return path;
}
public String getFileName(){
return fileName;
}
}

Unable to send value from Javascript file to Android Activity

I am trying to pass a value from a custom javascript file I have included after loading a URL in a webview.
I have checked this reference but it doesn't work when I am loading a website apart from a local index.html file.

mLoader = (RelativeLayout) findViewById(R.id.loader);
// Add javascript support to the webview
mWebView.getSettings().setJavaScriptEnabled(true);
// Enable pinch zoom controls on webview
mWebView.getSettings().setBuiltInZoomControls(false);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

And this is my script.js file:
document.getElementById("aadhaarNo").type= 'tel';
var myElem = document.getElementById('actionMessages');
Android.showToast("Hello World!");
if (myElem === null) {
console.log('does not exist');
}
else{
if (myElem.classList.contains('success')){
console.log('success');
}
}
I am trying to call the function from the script file to send the value to the Toast but the Toast doesn't appear.

Change "Context" to "Activity" in class JSInterface. Check the below edited code..
public class JSInterface {
private Activity mContext;
public JSInterface(Activity c) {
mContext = c;
}
#JavascriptInterface
public void showToast(String message) {
Toast.makeText(mContext, message, Toast.LENGTH_LONG).show();
}
}

Inject javascript file to my site with webview in android

I want to inject javascript file to my site. My site is a simple html page that is on server. I have injected css file. (with Manish's help)
So I can manage my simple html site with CSS now. But I want to manage it with javascript too. My jscript.js file is in asset folder. I want to have full access of javascript on my site. (Remember that, it is MY site) . please write the correct codes for me. Thankx.
Here is my MainActivity.java file:
package com.example.z5070.myapplication;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.util.Base64;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import java.io.InputStream;
public class MainActivity extends ActionBarActivity {
WebView webView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = new WebView(this);
setContentView(webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
injectCSS();
super.onPageFinished(view, url);
}
});
webView.loadUrl("http://www.example.com/");
}
private void injectCSS() {
try {
InputStream inputStream = getAssets().open("style.css");
byte[] buffer = new byte[inputStream.available()];
inputStream.read(buffer);
inputStream.close();
String encoded = Base64.encodeToString(buffer, Base64.NO_WRAP);
webView.loadUrl("javascript:(function() {" +
"var parent = document.getElementsByTagName('head').item(0);" +
"var style = document.createElement('style');" +
"style.type = 'text/css';" +
"style.innerHTML = window.atob('" + encoded + "');" +
"parent.appendChild(style)" +
"})()");
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}

Add a new method to inject javascript file.
private void injectJS() {
try {
InputStream inputStream = getAssets().open("jscript.js");
byte[] buffer = new byte[inputStream.available()];
inputStream.read(buffer);
inputStream.close();
String encoded = Base64.encodeToString(buffer, Base64.NO_WRAP);
webView.loadUrl("javascript:(function() {" +
"var parent = document.getElementsByTagName('head').item(0);" +
"var script = document.createElement('script');" +
"script.type = 'text/javascript';" +
"script.innerHTML = window.atob('" + encoded + "');" +
"parent.appendChild(script)" +
"})()");
} catch (Exception e) {
e.printStackTrace();
}
}
Call both methods: injectCSS() and injectJS() after page finishes loading.
webView.setWebViewClient(new WebViewClient() {
#Override
public void onPageFinished(WebView view, String url) {
injectCSS();
injectJS();
super.onPageFinished(view, url);
}
});
I hope this solves the problem.
Be wary of how onload events defined inside inject js file would behave.

Some refinements to previous answer. Suppose we use Cyrillic words. Result would be a garbaged strings. It's not good. With code below you can use non-english chars in content. Just add additional url-encoding/decoding to your code and you good to go. Reedited version below.
private void injectJS() {
try {
InputStream inputStream = getAssets().open("jscript.js");
byte[] buffer = new byte[inputStream.available()];
inputStream.read(buffer);
inputStream.close();
// preserve non-english letters
String uriEncoded = URLEncoder.encode(new String(buffer, "UTF-8"), "UTF-8").replace("+", "%20");
String encoded = Base64.encodeToString(uriEncoded.getBytes(), Base64.NO_WRAP);
webView.loadUrl("javascript:(function() {" +
"var parent = document.getElementsByTagName('head').item(0);" +
"var script = document.createElement('script');" +
"script.type = 'text/javascript';" +
// don't forget to use decodeURIComponent after base64 decoding
"script.innerHTML = decodeURIComponent(window.atob('" + encoded + "'));" +
"parent.appendChild(script)" +
"})()");
} catch (Exception e) {
e.printStackTrace();
}
}

LoadUrl Javascript not loading at all

could someone please help me. I'm having difficulty with LoadUrl and javascript.
The code below seems to work sorta ok (killing the app then trying again makes it work) on my old HTC running 2.3 however, my Xperia Z which runs the latest Android gets stuck on "Attempting to get Comments".
The section of code it is sticking on is InjectJavaScript() wherein this fails to LoadUrl (I know this as onPageFinished is never called). The strange thing is statistics part of the code works fine and its identical.
Sorry its pretty messy code...

I see that FetchFromEmpathica is going to be called again when you load the second page, and you set again a new WebViewClient() to the webview, put it on the setup() method so it is going to be called once.
Make sure that your Xperia is 4.1.2, nonetheless look what is mentioned on
Reference: JavascriptInterface methods in WebViews must now be annotated
Beginning in Android 4.2, you will now have to explicitly annotate public methods with #JavascriptInterface in order to make them accessible from hosted JavaScript. Note that this also only takes effect only if you have set your app's minSdkVersion or targetSdkVersion to 17 or higher.
Add it and import android.webkit.JavascriptInterface
So the code will be up-to-date to last versions.
#JavascriptInterface
public void processHTML(final String html)
{
//code
}
