[Q] Alawyas report network not available when using NewtorkInfo program

share [g+] share [fb] share [tw]
I have wrote a program to check if the network is available or not. Here is my simple code:
Code:
public boolean isNetworkAvailable() {
Context context = getApplicationContext();
ConnectivityManager connectivity=ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity == null) {
boitealerte(this.getString(R.string.alert),"getSystemService rend null");
} else {
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null) {
for (int i = 0; i < info.length; i++) {
if (info[i].getState() == NetworkInfo.State.CONNECTED) {
return true;
}
}
}
}
return false;
}
I run it on my Android phone, it always returns false but the network is available and I can make calls. Any suggestions>.

Hi!
Can you elaborate here? I have no idea what you are attempting. Can you explain in plain english? And perhaps I can find you a place for help.

it appears as though it is listing which apps either stay awake on sleep, or launch at boot. Can anybody confirm this?
And in this file, it looks like it might be controlling the apps in the apploop, maybe...
file is android/microntek/c.java

Let me know what you guys think.

You are absolutely correct. Check out the thread on the Malaysk ROM for the PX5. A member, Nico84, is working with the same files. You guys may want to join forces on this.
Johan

Thanks for that, does that work on the Stock firmware, or only on Malaysk's Custom ROM?

Not sure, but I believe it will work on stock. Needs to be rooted I suppose. Contact Nico84 for details, I am not an experienced Android developer.

I did, thanks for the lead on that, exactly what I was looking for. It looks like it should work on stock firmware so ill probably give it a try

So I took Nico84's MTCManager and tried to decompile and add spotify and accuweather to it, and recompile it. But then the actualy MTCManager did not work, so not sure what I did wrong.

You have to compile it with original signature, not testkeys. You can use "tickle my android"

Bummer, tickle my android does not seem to work on mac which is all I have, is there any other way to compile with original signature with apktools? Or would it be possible to make me a version that allows spotify and accuweather to remain open, that would be great.

Ok so I found the documentation on signatures for the APKtool, but it still didnt work. Just to be clear I started this command
Code:
apktool d MTCManager.apk
then I made the changes to the smali.d file, and then recompiled with this command
Code:
apktool b MTCManager/ -c
Is there something I am doing wrong? (The location of files is not exact, bare in mind I am doing this on a mac via terminal so I simply drag and drop the file which returns the path it needs.)

On second try I was able to get this to work. The above commands worked perfectly, my guess is I messed something up the first time around.

For PX3:
when the unit comes back from sleep it sends Intent com.cayboy.action.ACC_ON
when it goes to sleep it sends com.cayboy.action.ACC_OFF

How to crop bitmaps according to size of a custom view

Trying to make a motion detection app. The intention is to make the app take pictures when motion is detected by comparing two images. Up to this part, the app is working fine.
Requirement:
To specify area of detection by a custom view. So that, the pictures will be captured only if a motion is detected inside the defined area by calculating the detection area.
What I have tried:
Created a movable custom view, like a crop view of which the dimensions (`Rect`) are saved in the preference each time when the view is moved.
In the detection thread I tried setting the width and height from the preference like
Code:
private int width = Prefe.DetectionArea.width();
private int height = Prefe.DetectionArea.height();
But it didn't work.
What is not working:
The motion detection from inside the custom view is not working. I believe that the bitmaps must be cropped according to the size of the custom view.
Please help me by explaining how this could be achieved so that the motion detection will happen according to the size of the custom view. I'm new to android and trying to self learn, any help is appreciated.

I can't take high quality picture by android camera

I'm taking a picture via camera with low or sometimes medium quality and camera return correct uri and picture to my app.
When i set my camera high quality in Samsung phones not return picture and in HTC phones give me an error nullpointerexception: uri (or crash my app in another phones) but in low quality works perfectly.
my code:
Code:
imCamera.setOnClickListener(new
View.OnClickListener() {
@Override
public void onClick(View v) {
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, "New Picture");
values.put(MediaStore.Images.Media.DESCRIPTION, "From your Camera");
imageUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
if (intent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(intent, 100);
}
show.dismiss();
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
...
try {
Bitmap thumbnail = MediaStore.Images.Media.getBitmap(
getContentResolver(), imageUri);
String photoPath = getRealPathFromURI(imageUri);
ExifInterface ei = new ExifInterface(photoPath);
int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION,
ExifInterface.ORIENTATION_UNDEFINED);
Bitmap rotatedBitmap = null;
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
rotatedBitmap = rotateImage(thumbnail, 90);
break;
case ExifInterface.ORIENTATION_ROTATE_180:
rotatedBitmap = rotateImage(thumbnail, 180);
break;
case ExifInterface.ORIENTATION_ROTATE_270:
rotatedBitmap = rotateImage(thumbnail, 270);
break;
case ExifInterface.ORIENTATION_NORMAL:
default:
rotatedBitmap = thumbnail;
}
if (rotatedBitmap != null) {
ivImage.setImageBitmap(rotatedBitmap);
File tempFile = GetTempFile(rotatedBitmap);
if (tempFile != null)
crImage = tempFile;
}
} catch (Exception e) {
e.printStackTrace();
}
i tested it on android: 4,5,6,7
But it still give me error when quality is high.
