I need help with my code on Android, I've been trying and searching for 3 hours and no luck
so what I've is a library that call MediaPlayerSDK, I'm using it in my application to play videos. The library is using SurfaceView to play video. Now, I've to include getSurfaceView().setZOrderOnTop(true) to the player so I can show the video otherwise it will not be shown ( only audio). But, when I'm using getSurfaceView().setZOrderOnTop(true) I cannot put any view on top of player. I want to build a controllers to the player but I couldn't. I've tired getSurfaceView().setZOrderMediaOverlay(true) and same problem the video is not shown.
The XML code for Activity:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent">
<FrameLayout
android:id="#+id/playerViewLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:text="...."
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/ChTitle"
android:textColor="#color/white"
android:textStyle="bold"
android:layout_marginLeft="5dp"/>
<veg.mediaplayer.sdk.MediaPlayer
android:id="#+id/playerView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true" />
</FrameLayout>
</RelativeLayout>

I'm developing a cordava plugin that manages my expansion files for android. The reading of an expansion file works, but I have problems with downloading them.

My problem is that onServiceConnected is never called although I call mDownloaderClientStub.connect(context);
Does anybody know why it is not called? I'm getting no error either.
The service connection could not be established because you pass an incorrect Class object into the expansion library methods.
You should change the argument in the call to DownloaderClientMarshaller from DownloaderService.class to MyDownloaderService.class or whichever class you use to extend the base DownloaderService. Also, make sure that your service is defined in your app's manifest.
// use the correct service class!
int startResult = DownloaderClientMarshaller.startDownloadServiceIfRequired(context, pendingIntent, MyDownloaderService.class);
// when creating a stub also
mDownloaderClientStub = DownloaderClientMarshaller.CreateStub(this, MyDownloaderService.class);
I recommend using the updated Downloader Library included in Better APK Expansion package. It has this and other issues fixed and also provides simplified API that minimizes chances to shoot yourself in the foot.
I am realizing pdf viewer function using APV library
when I load pdf file using APV library I mentioned, some part of pages are invisible and sometimes not.
Invisible parts are sometimes paragraph and sometimes picture etc. I think it does not depend on object but trial.
Does anyone have similar problem? If anyone knows, please let me know.
I attached 2 picture that have same page, one normal and the other abnormal.

I am using magtek card reader audio uDynamo device and i am integrating sdk with my android application. But when i am trying to open device through openDevice() method. Application unfortunately stopped. Why its doing like this ?
This is what i am doing
m_SCRA.setConnectionType(MTConnectionType.Audio);
m_SCRA.setAddress(m_deviceAddress);
m_connectionState = MTConnectionState.Connected;
// here its stopping
m_SCRA.openDevice();

I was facing the same issue. It turned out that I forgot audio recording runtime permission.
private void checkRecordPermission() {
if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.RECORD_AUDIO)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.RECORD_AUDIO},
123);
}
}

Until now i used , before working with Frgment:
package com.application.i;

import android.os.Bundle;
public class FTDI extends Activity
{

super.onCreate(savedInstanceState);

}
As i press the button on my main screen it stuck, the hole application finished with error.
Edit:
My problem is that I need a UI to check this class and then to put it as a Service, I know how to Service it, without user interface.
I changed the code to be an activity and it looks :

Any suggestions?
To attach a fragment to an Activity you have two ways:
1) Declare the fragment inside the activity's layout file.
2) Programmatically add the fragment to an existing ViewGroup.
In my opinion you can use the second way, so basically you need a ViewGroup in the activity where to put the Fragment; something like a Layout can be good for that.
When you have the place where to insert the Fragment you can insert it using the LayoutInfleter.
Fragment fragment = new YourFragment();
getLayoutInflater.inflate(R.id.youLayoutContainer, fragment, false);
Take a look at the page below for more informations:
http://developer.android.com/guide/components/fragments.html
I wanted to know how can I pass a variable from private void to OnCreate?
public final Handler mHandler = new Handler() {
#Override
public void handleMessage(Message msg) {
switch (msg.what) {
case MESSAGE_STATE_CHANGE:
if(D) Log.i(TAG, "MESSAGE_STATE_CHANGE: " + msg.arg1);
switch (msg.arg1) {
case BluetoothChatService.STATE_CONNECTED:
setStatus(getString(R.string.title_connected_to, mConnectedDeviceName));
mConversationArrayAdapter.clear();
break;
case BluetoothChatService.STATE_CONNECTING:
setStatus(R.string.title_connecting);
break;
case BluetoothChatService.STATE_LISTEN:
case BluetoothChatService.STATE_NONE:
setStatus(R.string.title_not_connected);
break;
}
break;
case MESSAGE_WRITE:
byte[] writeBuf = (byte[]) msg.obj;
// construct a string from the buffer
String writeMessage = new String(writeBuf);
mConversationArrayAdapter.add("Me: " + writeMessage);
break;
case MESSAGE_READ:
byte[] readBuf = (byte[]) msg.obj;
// construct a string from the valid bytes in the buffer
String readMessage = new String(readBuf, 0, msg.arg1);
int k=Integer.parseInt(readMessage.replaceAll("[\\D]",""));
mConversationArrayAdapter.add(readMessage);
Toast.makeText(getApplicationContext(),"ciao"+k ,Toast.LENGTH_SHORT).show();
break;
case MESSAGE_DEVICE_NAME:
// save the connected device's name
mConnectedDeviceName = msg.getData().getString(DEVICE_NAME);
Toast.makeText(getApplicationContext(), "Connected to "
+ mConnectedDeviceName, Toast.LENGTH_SHORT).show();
break;
case MESSAGE_TOAST:
Toast.makeText(getApplicationContext(), msg.getData().getString(TOAST),
Toast.LENGTH_SHORT).show();
break;
}
}
};
This is OnCreate:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mvc = (Button) findViewById(R.id.button1);
mvc.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
new Thread(new Runnable() {
public void run() {
while (progressStatus < 1000) {
Random r = new Random();
int i1 = r.nextInt(1000);
if (i1 > progressStatus){
progressStatus = i1;
}
else {
progressStatus = progressStatus;
}
// Update the progress bar and display the current value in the text view
handler.post(new Runnable() {
public void run() {
progressBar.setProgress(progressStatus);
}
});
try {
// Sleep for 200 milliseconds. Just to display the progress slowly
Thread.sleep(500);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
}
});
res = (Button) findViewById(R.id.button2);
res.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
progressBar.setProgress(0);
progressStatus=0;
}
});
if(D) Log.e(TAG, "+++ ON CREATE +++");
// Set up the window layout
progressBar = (ProgressBar) findViewById(R.id.progressBar1);
// Get local Bluetooth adapter
mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
// If the adapter is null, then Bluetooth is not supported
if (mBluetoothAdapter == null) {
Toast.makeText(this, "Bluetooth is not available", Toast.LENGTH_LONG).show();
finish();
return;
}
}
I pass the variable k, is there a method? or I have to go to a public int? I do not know how to solve. Thank you in advance!
Umm, why not make k a Global Variable?
Add int k inside starting of your class
For example :
...
public class MainActivity extends Activity {
int k;
//onCreate and other methods
}
...
Change
int k = =Integer.parseInt (readMessage.replaceAll.replaceAll("[\\D]",""));
to
k = =Integer.parseInt(readMessage.replaceAll.replaceAll("[\\D]",""));
as you've already made k an integer.
Then you can use k anywhere in your class
