Android explictly free memory without calling System.GC - java

I have an Android App, in which I have below class containing fields of both native (C++) objects wrapped with JNI, and other java objects:
class MyClass
{
Node nativeNode; // containing Native objects wrapped using NDK and JNI
long otherVars; // some java instances
public void dispose()
{
freeNativeNode();
}
}
In my app, I continuously create instances of MyClass:
for(int i=0;i<1000;i++)
{
MyClass obj = new MyClass();
...
obj.freeNativeNode(); // Here, free native resources (A)
//System.gc(); // Here explicitly collect memory (B)
}
The app crashes when i is bigger than some number, e.g. when i>400 or i>450.
Since I have freed the native memory explicitly as in line (A) above, so I think there should be no memory leak, and java shall use garbage collection to revoke the memory. But the app crashes, and I suspect it might be a memory leak problem.
As I know, it is possible to free the managed memory in Java by calling:
System.GC();
I tried to call this in (B) above, however, the app crashes more often, and say when i > 60, it already crashes.
My questions are:
[1] Should I call System.GC() explicitly? As many have different opinions on calling this ourselves, and some say this is not a good practice.
[2] How do I elegantly free the memory in the loop to avoid crash?
Edit: I understand it is less appropriate to print full log here, but it might be useful to get the whole picture for troubleshooting the problem.
From the log, it seems to be not a memory leak problem, but one of my colleague believes so, and I have no strong evidence showing this is NOT, :)

[1] Should I call System.GC() explicitly? As many have different
opinions on calling this ourselves, and some say this is not a good
practice.
Probably not. As previously mentioned by user3580294, System.GC() is really only a suggestion to the VM and what it does when you call that method directly is totally up to the implementation. I would never use this function to prevent a program from crashing.
[2] How do I elegantly free the memory in the loop to avoid crash?
What exactly is using up all the memory? Clearly when MyClass is
constructed some native resouces are being created... Are these JNI
objects? Are they C alloced memory?
I am going to go out on a limb here based on the backtrace and say that the objects eating up all your memory are JNI objects that were created in C/C++ (probably on a separate thread) and passed back to the JVM. Try calling DeleteLocalRef() on the JNI object(s) that are passed back to the VM.
Again, my above suggestion is based on a lot of assumption. You really need to attach a memory profiler like jvisualvm to the JVM to see exactly what is using up all the memory and then determine why the GC didn't catch it. (Hint: there is probably still a reference to it)

This Error Force close my app when I'm inspecting my table : signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x10

I have table in my application and I'm Running my app on Huawei y9 and this error pops up after a 30 sec and force close my application. I link my other question that I put the code of my table btw Im ussing implementation "androidx.room:room-runtime:2.3.0" and
annotationProcessor "androidx.room:room-compiler:2.3.0" but I don't think this casing the error.
my Error :

Sometimes the code works but sometimes it doesn't... but when it occurs, it does so before the value of i reaches 449. I thought it had something to do with my jni code. but after commenting and deleting everything that would call a c code, the error still occurred.
Thank you for your help...

Fatal signal 11 in background thread only on 4.4.2

I have an activity that displays a screenshot of a map fragment, along with some other things. Everything shows up perfectly until a second or two later when the app crashes. This is only happening on Android phones using 4.4.2 kitkat, but not on tablets. After the first attempt to load this view, it will sometimes crash before even displaying anything when setContentView is called. Since it crashes at a different time each time I test, I assume something is happening on a background thread, and since it's a Fatal signal 11 I assume it's some sort of strange memory problem, but other than that I really have no clue what's going on.
Here's the activity:
public class TransactionDetailActivity extends CommonActivity implements Animation.AnimationListener {
private TransactionDetail _transaction = null;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.transaction_detail);
getActionBar().setDisplayHomeAsUpEnabled(true);
MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
if (mapFragment.getMap() != null) { // can be null if google play services isn't installed
mapFragment.getMap().getUiSettings().setZoomControlsEnabled(false);
}
Intent intent = getIntent();
String transactionReceiptNumber = intent.getStringExtra("transactionReceiptNumber");
loadTransactionDetail(transactionReceiptNumber);
ClipDialog.showDialog(this, getString(R.string.transaction_detail_loading));
}
#Override
public void onPause() {
super.onPause();
if (_runAnimation) {
final ImageView mapScreenshot = (ImageView) findViewById(R.id.map_screenshot);
MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
if (mapFragment.getMap() != null) {
mapFragment.getMap().snapshot(new GoogleMap.SnapshotReadyCallback() {
#Override
public void onSnapshotReady(Bitmap snapshot) {
mapScreenshot.setImageBitmap(snapshot);
Bitmap screenshot = Rotate3dAnimation.takeScreenshot(TransactionDetailActivity.this);
ImageView imageView = (ImageView) findViewById(R.id.screenshot);
imageView.setImageBitmap(screenshot);
findViewById(R.id.container).setVisibility(View.GONE);
disableActionBarAnimation();
getActionBar().hide();
imageView.startAnimation(new Rotate3dAnimation(false));
}
});
}
}
}
#Override
public void onResume() {
super.onResume();
if (_runAnimation) {
View imageView = findViewById(R.id.screenshot);
if (imageView != null) {
Rotate3dAnimation anim = new Rotate3dAnimation(true);
anim.setAnimationListener(this);
imageView.startAnimation(anim);
}
_runAnimation = false;
}
}
#Override
public void onAnimationEnd(Animation animation) {
ImageView mapScreenshot = (ImageView) findViewById(R.id.map_screenshot);
mapScreenshot.setImageBitmap(null);
ImageView imageView = (ImageView) findViewById(R.id.screenshot);
imageView.setImageBitmap(null);
findViewById(R.id.container).setVisibility(View.VISIBLE);
disableActionBarAnimation();
getActionBar().show();
}
private void loadTransactionDetail(String receiptNumber) {
ClipAPIClient.getInstance().getAPI().transactionDetail(ClipDataManager.getInstance().getCurrentUser().merchant.id, receiptNumber, new Callback() {
#Override
public void success(Object object, Response response) {
_transaction = (TransactionDetail) object;
configureViewForTransaction();
ClipDialog.hideDialog();
}
#Override
public void failure(RetrofitError error) {
ClipDialog.showDialogForDuration(TransactionDetailActivity.this, getString(R.string.transaction_detail_error));
L.e(error, "Transaction detail error");
AnalyticsClient.logError("TransactionDetail", error);
}
});
}
private void configureViewForTransaction() {
findViewById(R.id.map_container).setVisibility(View.VISIBLE);
findViewById(R.id.scroll_view).setVisibility(View.VISIBLE);
LatLng coordinate = new LatLng(new Double(_transaction.latitude), new Double(_transaction.longitude));
MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
if (mapFragment.getMap() != null) { // can be null if google play services isn't installed
mapFragment.getMap().addMarker(new MarkerOptions().position(coordinate));
mapFragment.getMap().moveCamera(CameraUpdateFactory.newLatLngZoom(coordinate, 14));
}
}
}
Here's the xml involving the map fragment:
<?xml version="1.0" encoding="utf-8"?>

On a 4.4.2 tablet, which doesn't crash, this is what shows after the view is all loaded:
D/dalvikvm(27019): GC_FOR_ALLOC freed 1137K, 14% free 12105K/14048K, paused 25ms, total 25ms
So it turns out that the crash was caused by an SSL error. I was using an older version of Retrofit that was causing bugs with not only google maps, but also with a Webview. The solution was to upgrade to the latest version of retrofit. Thanks for the suggestions.

Native heap android OOM hardware acceleration

first off I'm using a Nexus 7 (the 2013 one with the 1080p screen) running android 4.4(kitkat) and using eclipse with the adb pluggin for windows(64bit I think). My apps minSdkVersion is set to 11 and only operates in the landscape orientation.
The problem is I keep getting a OOM error after leaving my app run for a while. My dalvik heap remains constant at around 25~MB but using Debug.getNativeHeapAllocatedSize() and Debug.getNativeHeapSize() it says my native heap size is constantly increasing until the app crashes from a OOM error.
I'm using hardware acceleration by declaring android:hardwareAccelerated="true" in my manifest and using setLayerType( View.LAYER_TYPE_HARDWARE , null ) in my SurfaceView constructor to set it to be hardware accelerated.
(Using setLayerType( View.LAYER_TYPE_HARDWARE , null ) was my problem, I removed it and the memory leak stopped).
Weird thing is once I press the home button then go back to my app the native heap resets back to its initial value.
My proof the dalvik heap is remaining constant and the native heap is growing is from these messages in LogCat:
debug.native heap : allocated 191.45MB of 191.73MB (0.28MB free)
debug.VM heap memory: allocated 23.00MB VM Heap Size: 31.00MB MaxHeapSize: 192.00MB
: availMemory 634.95MB , lowMemory? false , threshold 96.00MB
: canvas.isHardwareAccelerated() = true
: GC_FOR_ALLOC freed 4566K, 30% free 22608K/32236K, paused 32ms, total 32ms
: debug. =================================
: debug.native heap : allocated 197.01MB of 197.27MB (0.26MB free)
: debug.VM heap memory: allocated 22.00MB VM Heap Size: 31.00MB MaxHeapSize: 192.00MB
: availMemory 629.38MB , lowMemory? false , threshold 96.00MB
Then once the native heap is full i get the error:

I want to know how to prevent native heap memory leaks since i have no idea how to alloc on the native block over the dalvik heap.
I solved the issue by the way, just want to write it out to help other people since I couldn't find an answer to this from days of searching.
I spent days looking for a solution to why my native heap was increasing and my dalvik heap remained constant. After many questions and android documentation pages read i eventually tried to shut off hardware acceleration since I came across a OOM question relating the two already.
I removed the line setLayerType( View.LAYER_TYPE_HARDWARE , null ) from my SurfaceView and the problem went away. I added that line after some advice from some suggestions on trying to get hardware acceleration turned on and i never really understood what i was doing there. For some reason that line caused about 1mb/2seconds to be added to the native heap until my program crashed.
So to anyone who's looking for solutions to problems try one thing at a time and understand what your trying before you copy paste it to your code.
I still don't know why that caused the native heap to constantly increase though.
I hope this helps someone with OOM native heap issues.
when animation over
try to add setLayerType( View.LAYER_TYPE_SOFTWARE , null) in order to turn off hardware acceleration
maybe solove the issue?

Android: JNI crash

i'm developing android app that uses Clang via C API (libclang) for ARM.
I've wrote wrapper to invoke clang_..() functions and map data between Java<->native code. So the app is working for few times and then crashing. It's interacting with native code from java background thread (if that helps).
My idea about what's wrong is:
i'm trying to delete already deleted pointer
there is a memory leak in my code/clang and heap is fully allocated
concurrency issue
Any thoughts are highly appreciated:
