I'm working on a mobile application that uses Webview to access a jQuery Mobile page, the problem is the Appcache is not saving my page, but it does save on browsers though, I've been searching for solutions, but none of them seemed to work in my case.
Any help is deeply appreciated!
Here's my Webview code:
package com.enlac.tasking;
import java.io.File;
import com.enlac.tasking.R;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebStorage;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebViewActivity extends Activity {
private WebView webView;
#SuppressWarnings("deprecation")
#SuppressLint("SetJavaScriptEnabled") public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setDatabaseEnabled(true);
webView.getSettings().setDomStorageEnabled(true);
String sDataPath = this.getApplicationContext().getDir("database", Context.MODE_PRIVATE).getPath();
webView.getSettings().setDatabasePath(sDataPath);
webView.getSettings().setSavePassword(true);
webView.getSettings().setAllowContentAccess(true);
webView.getSettings().setAllowFileAccess(true);
File dir = getCacheDir();
if (!dir.exists()) {
dir.mkdirs();
}
webView.getSettings().setAppCachePath(dir.getPath());
webView.getSettings().setAppCacheEnabled(true);
webView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
webView.setWebViewClient(new Callback());
webView.setWebChromeClient(new webChromeClient());
webView.loadUrl("I removed the link because I don't have the rights to show some stuff on it");
}
private class Callback extends WebViewClient{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return (false);
}
}
private class webChromeClient extends WebChromeClient

}
}
}

I am trying to create a webview app. I tried to add the access to manifest but it didn't change anything. On the chrome browser the camera works, I can't understand what should I do.
1. This is the manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="i.astiapp.astiappadmindev">
<uses-permission android:name="android.permission.INTERNET" />

<uses-feature android:name="android.hardware.camera" android:required="true" />
<uses-feature android:name="android.hardware.camera.front" android:required="true" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />

</application>
</manifest>
2. Main Activity

}
});
myWebView.setWebViewClient(new WebViewClient() {
#Override

super.onPageStarted(view, url, favicon);
chromeProgressBar.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
chromeProgressBar.setVisibility(View.GONE);
}
});
}
#Override

if (progressValue == 100) {
chromeProgressBar.setVisibility(View.INVISIBLE);
}
}
public class WebViewController extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
#Override
public void onBackPressed()
{
if(myWebView.canGoBack())
myWebView.goBack();
else
super.onBackPressed();
}
}
I don't think I should post the PHP file since on the chrome browser the page works. It happens like this:
You enter the page
Chrome browers asks you to give you the permission to the camera
The camera starts working
Fixed it. I had to add the permession to the code:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
int hasCameraPermission = checkSelfPermission(Manifest.permission.CAMERA);
List<String> permissions = new ArrayList<String>();
if (hasCameraPermission != PackageManager.PERMISSION_GRANTED) {
permissions.add(Manifest.permission.CAMERA);
}
if (!permissions.isEmpty()) {
requestPermissions(permissions.toArray(new String[permissions.size()]), 111);
}
}
But for this to work I had to add the manifest file too:
import android.Manifest;
I recently made a website (www.fruitboompje.com).
Now I am trying to make a mobile android app for my website.
The mobile version of the site works great in chrome!
But with this test app I have now it will not load the video/music...
Can somebody help me with this?
MainActivity.java
package com.fruitboompje.music;
import android.net.Uri;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MainActivity extends AppCompatActivity {
private WebView mWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.activity_main_webview);
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.fruitboompje.com/");
mWebView.setWebViewClient(new WebViewClient());
mWebView.setWebViewClient(new MyAppWebViewClient());
}
}
This is my AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>

Thank you for helping Shark! Adding the YouTube API worked fine for me!
Hello I'm working on programming a Google Maps WebView. I was trying to track and display my own location. When I press the button, it loads for a while and it said that Google Maps couldn't determine my precise location. I tried running it on Android 5.1 Api 22 Lollipop, it still doesnt work.

I am implementing a simple application executing a background service, I am not able to start the service, following is my Manifest & Code, the service class is properly resolved ( reading resources ), inheriting from IntentService ( and implementing the req methods ) doesn't resolve the problem as-well...
Why does the Background service doesn't start?
any help will be appreciated.

import android.app.Service;
import android.content.Intent;
import android.R.*;
import android.os.IBinder;
import java.io.IOException;

}
#Override

return Service.START_NOT_STICKY;
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
super.onCreate();
}
}
Activity code:
package com.newcomp.vagent;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;
public class MainActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
final String strSvcName = getResources().getString(R.string.startup_service);
//setContentView(R.layout.main);
Toast.makeText(getBaseContext(), String.format("Hello from '%s'", strSvcName), Toast.LENGTH_LONG).show();
Class cls = null;
try {
cls = getClassLoader().loadClass(strSvcName);
startService(new Intent(this, cls));// Starts the service
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
//finish();
}
}
The problem was simple, the service was actually starting but since android:process=":captureService" was specified it was starting on a separate process, one that is not connected by the debugger, either specifcally connecting to the service process, OR, omitting android:process=":captureService" resolve the problem.
I'm trying to create my first app, the browser for android with this code already done, but needed to adapt to my necessity. I still do not know java, and the examples I find I can not make it work.
I need help and reading.
How can remove the titlebar and remain the browser in fullscreen?
for later viewing and interacting with my application in jquery mobile

1 - in your layout, set the WebView to match_parent in both layout_width and layout_height
2 - in your code, add these lines:
super.onCreate(savedInstanceState);
// Hiding Title bar of this activity screen
getWindow().requestFeature(Window.FEATURE_NO_TITLE);
// Making this activity full screen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
in place of the existing
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
If your IDE is NOT SET to add the missing imports, just add the following line to your imports:
import android.view.Window;
import android.view.WindowManager;
update your manifeist like this :
only mentioning one thing:
android:theme="#android:style/Theme.NoTitleBar"
