I am trying to establish USB communication as host. I am following the examples here http://developer.android.com/guide/topics/usb/host.html but I cannot get this working. Here is my code:
private static final String ACTION_USB_PERMISSION = "com.multitools.andres.LCView";
UsbDevice device;
//Pide permisos al usuario para comunicacion con el dispositivo USB
private final BroadcastReceiver mUsbReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (ACTION_USB_PERMISSION.equals(action)) {
synchronized (this) {
UsbDevice device = (UsbDevice)intent.getParcelableExtra(UsbManager.EXTRA_DEVICE);
if (intent.getBooleanExtra(UsbManager.EXTRA_PERMISSION_GRANTED, false)) {
if(device != null){
//call method to set up device communication
}
}
else {
Log.d(TAG, "permission denied for device " + device);
}
}
}
}
};
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if(DEBUG) Log.i(TAG, "onCreate() -> MainMenu");
actionBar = getActionBar(); //obtengo el ActionBar
actionBar.setDisplayHomeAsUpEnabled(true); //el icono de la aplicacion funciona como boton HOME
//Menu
setListAdapter(new ArrayAdapter<String>(MainMenu.this, android.R.layout.simple_list_item_1, MenuNames));
//USB
if(DEBUG) Log.i(TAG, "Setting UsbManager -> MainMenu");
UsbManager mUsbManager = (UsbManager) getSystemService(Context.USB_SERVICE);
PendingIntent mPermissionIntent;
if(DEBUG) Log.i(TAG, "Setting PermissionIntent -> MainMenu");
mPermissionIntent = PendingIntent.getBroadcast(this, 0, new Intent(ACTION_USB_PERMISSION), 0);
if(DEBUG) Log.i(TAG, "Setting IntentFilter -> MainMenu");
IntentFilter filter = new IntentFilter(ACTION_USB_PERMISSION);
if(DEBUG) Log.i(TAG, "Setting registerReceiver -> MainMenu");
registerReceiver(mUsbReceiver, filter);
if(DEBUG) Log.i(TAG, "Setting requestPermission -> MainMenu");
mUsbManager.requestPermission(device, mPermissionIntent);
}
I get the Force Close dialog when I uncomment the line mUsbManager.requestPermission(device, mPermissionIntent); If I comment it, I don't get the force close but it doesnt work. I think the problem is in:
private static final String ACTION_USB_PERMISSION = "com.multitools.andres.LCView";
On Google's example it is as:
private static final String ACTION_USB_PERMISSION = "com.android.example.USB_PERMISSION";
But I dont know what exactly I have to put there and i could not find any explanation about that. What i have to put there or where is my error ? Here is the LogCat i am getting when i start my application:

Thanks you :)
That string is just a marker so you recognize the intent that is returned when you call registerReceiver(mUsbReceiver, filter);. That isn't the problem.
I think the problem is here:
UsbManager mUsbManager = (UsbManager) getSystemService(Context.USB_SERVICE);
This line is supposed to get you your USB Manager, but as far as I recall not all phones have to support the Android USB Accessory API. This line is probably just assigning null to mUsbManager which then causes you NullPointerException when you call a method on it further down in the code. Trying checking if that isn't null before making a call on it.
For more info, checkout these links:
http://developer.android.com/guide/topics/usb/index.html
http://developer.android.com/guide/topics/usb/accessory.html
EDIT:
I think I see what the issue is now. You're right, it's not the USB Manager. It's the UsbDevice object (device). It is never initialized anywhere in your code. In this line :
mUsbManager.requestPermission(device, mPermissionIntent);
you're basically firing off an intent to ask the user if it's okay for you to work with the device represented by the UsbDevice object device. However when this call gets fired device has not yet been initialized (and therefore has the default value of null). So when you try to request permission you end up getting a NullPointerException instead of the expected result. To fix this you need to figure out which device you want to connect to and assign it to device. Look in here, under "Enumerating devices" to figure out different ways to do that. One way, if you know the name of the device you want to connect to, is to make the following calls after you retrieve the Usb Manager:
HashMap<String, UsbDevice> deviceList = mUsbManager.getDeviceList();
device = deviceList.get("<deviceName>");
(Obviously, you would replace <deviceName> with the actual name of the device.
minSdkVersion must >= 12
To enable USB host API support you should add a file named
android.hardware.usb.host.xml and containing the following lines:
<permissions>
<feature name="android.hardware.usb.host"/>

For gaming better to use genymotion dont use AVD that doesn't support EGL rendering and in android 4.4 use dalvik instead of ART ...
Hope you get my point.
Finally my app is working..!:D Problem is solved by updating and applying latest patch unity 4.6.6p1.. which removes the bug from older version .Hope this will help someone having a similar problem

how do i fix them?
every help will be apriciated.thank you for your kindness.
I had faced the same problem. I tried to fix it by a couple of ways, and both of them eventually worked!!
Go to onResume() at CaptureActivity.java. Comment the whole function except the line super.onResume(). Next, add the following lines into your activity:
#Override
public void onResume(){
super.onResume();
}
You could use the example from this link - http://khurramitdeveloper.blogspot.in/p/android-barcode-scan-using-zxing-library.html. It works for me without any hitch!
this is my first question, but this forum helped me a lot in the last 2 months!!!
I tried to make an "Gallery" on my Android app, i solved it for 1 Gallery, but after i tried to make more "Galleries", i got an error in my "OnCreate".
This is my onCreate:
public void onCreate(Bundle savedInstanceState) {
//try {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_combination);
Gallery h = (Gallery) findViewById(R.id.gallery_head);
h.setAdapter(new ImageAdapter_head(this));
h.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int position, long id) {
Toast.makeText(Create_combination.this, "" + position,
Toast.LENGTH_SHORT).show();
}
});
i make this for 3 times (for 3 Galleries)
My class "ImageAdapter:head":
public class ImageAdapter_head extends BaseAdapter {
int mGalleryItemBackground;
private Context hContext;
private Integer[] mImageIds_head = { R.drawable.layout, R.drawable.ic_launcher,
R.drawable.test2, R.drawable.layout, R.drawable.layout,
R.drawable.layout, R.drawable.layout };
public ImageAdapter_head(Create_combination create_combination) {
// TODO Auto-generated constructor stub
}
public void ImageAdapter(Context h) {
hContext = h;
TypedArray a = obtainStyledAttributes(R.styleable.Gallery1);
mGalleryItemBackground = a.getResourceId(
R.styleable.Gallery1_android_galleryItemBackground , 0);
a.recycle();
}
public int getCount() {
return mImageIds_head.length;
//return mImageIds_upper.length;
//return mImageIds_lower.length;
}
public Object getItem(int position) {
return position;
}
public long getItemId(int position) {
return position;
}
ImageView h = new ImageView(hContext);
#SuppressWarnings("deprecation")
public View getView(int position, View convertView, ViewGroup parent) {
h.setImageResource(mImageIds_head[position]);
h.setLayoutParams(new Gallery.LayoutParams(150, 100));
h.setScaleType(ImageView.ScaleType.FIT_XY);
h.setBackgroundResource(mGalleryItemBackground);
return (h);
}
}
And here are my Errors:

In one of my activities you can click on an image button and a dialog opens up to ask you to open up the Gallery. Once opened up you can click on one of those images in your gallery.
What I want that the clicked image is set as the image of the image button. This image should stay there even when the user kills the app (when he opens up the app again the chosen image should still be there).
I chose to do all this work with the shared preferences but can't get it working. I get an error when I click on an image in the gallery. Any suggestions??
UPDATE: The error I receive is:
Unfortunately, the process com.myname.android has stopped
Here is my code, beginning with the onActivityResult:
private String selectedImagePath;
private String mFileName;
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == PICK_FROM_FILE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
Log.v("IMAGE PATH====>>>> ",selectedImagePath);
}
storePath();
retrievePath();
convertPathToImage();
}
}
private void storePath() {
final SharedPreferences sPreference = getSharedPreferences(
"pref_key", MODE_PRIVATE);
final Editor spEditor = sPreference.edit();
spEditor.putString("img_path", mFileName);
spEditor.commit();
}
private void retrievePath() {
final SharedPreferences sharedPreference = getSharedPreferences(
"pref_key", MODE_PRIVATE);
if (sharedPreference.contains("img_path")) {
mFileName = sharedPreference.getString("img_path",
null);
}
}
private void convertPathToImage() {
File imgFile = new File(mFileName);
if(imgFile.exists()){
Bitmap myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
ImageButton myImage = (ImageButton) findViewById(R.id.image);
myImage.setImageBitmap(myBitmap);
}
}

This is probably a bug in Android. See http://code.google.com/p/android/issues/detail?id=29399. It shouldn't effect the app though which should still be able to get a result back from the gallery.

This is the problem. mFileName is null when you try to use it to create a new File. In retrievePath, when you try to pull "img_path" out of your preferences the default value is null, so I'm guessing it's getting set to null there. Check in the debugger to make sure mFileName is getting set to a valid String from your preferences.
