UnsatisfiedLinkError: Native method not found with .so file correctly put in Eclipse libs

I'm new in using native methods for Android. I got the errors as below even after I have make sure my armeabi, armeabi-v7a, mips and x86 with correct *.so file are put correctly in the folders.

As below is how I loaded my .so file:
static{
try {
System.loadLibrary("libMimasAr3D");
} catch (UnsatisfiedLinkError use) {
Log.e("JNI", "WARNING: Could not load libMimasAr3D.so");
}
}
Something extra (which I don't think that's the main issue)?
In the same file where I load my library, I have this method:
public static native void MIMAS_LoadModel(int ppModel);
Main Activity.java:
//Description: Load the model.
//Input: pModelPath - A file path to the saved model.
//Return: A pointer to the object of the model. NULL if loading is failed.
//Load image to MIMAS_SDK
MimasJNI.MIMAS_LoadModel("models/model.bin");
Kindly please help me with that. Thanks in advance!

loadLibrary() takes the name without "lib" prefix.
If you don't use RegisterNatives(), you should name the exported functions of your native library according to javah prescriptions, e.g. Java_com_arzap_mimas_MimasJNI_MIMAS_1LoadModel.
If the native code is C++, make sure the exported functions have extern "C" prefix to pervent name mangling.

Out of memory. InflateException Binary XML file Android

I have OutOfMemoryError while creating layout with a few images.
In line where logcat show me error i start declare TextView.
Error is on Samsung Galaxy S4.
When i run apps on HTC Desire X there is no error.

Your bitmap is too heavy. Resize it(e.g gimp) and try again.

I've stumble upon this problem too in most of HiDef devices such as Galaxy S4. It's because HiDef devices use xhdpi, xxhdpi and so on to inflate drawable. When they didn't find it, they scale it programmatically thus cause OutOfMemory Exception. So the solution is to put your drawable on those hdpi, xhdpi, xxhdpi, xxhdpi folder accordingly.

thanks for your help!

Caused by: java.lang.NoSuchMethodException: <init> [class android.content.Context, interface android.util.AttributeSet]
it means that your custom view Panel is missing the constructor with the context and attributeset:
public void Panel(Context context, AttributeSet att) {
super(context,att)
}
which is used when the custom view is inflated from the xml

Android project crashes whenever a Maps fragment is in the layouts xml

I'm currently trying to build an app with Google Map APIv2 for Android. I have spent a few hours trying to debug this error and have found nothing. I even tried creating
All I ever get when I try to include maps API fragment is "Unfortunately, myapp has"

Use below in the initialization of dialog -
Dialog mDialog= new Dialog(YourActivityName.this);

You're leaking your Window. This happens when your Activity creates the Dialog and you try recreating the Dialog instead of re-using your old dialog/dismiss that previous dialog.
