Framedrops --> Ideas for better Android Game rendering?

Framedrops --> Ideas for better Android Game rendering? - android

my simple application suffers from framedrop. I think this is due to my rendering method:
public void draw(Canvas canvas) {
drawBackground(canvas);
drawPlayer(canvas);
drawEnemy(canvas);
}
As you can see, the background gets drawn every single time this method is called, as well as player and enemy... the "drawBackground(canvas)" looks kinda like this:
public void paintBackground(Canvas canvas) {
canvas.drawBitmap(background, 0, 0, null);
}
drawPlayer and drawEnemy draw circles at the position my player/ or enemyobject returns.
Is there any better solution for displaying background, player and other objects, without constantly redrawing them?

My Application freezes

I am developing an android application for fingerprint reader, my operations include verifying user fingerprint(continuously), and registering new fingerprints(getting fingerprints from web API).
I am using Morpho MSO 1300 fingerprint reader.
when I run my application I am constantly getting following logcat messages

As I increase data in my application, say I get 1000 users from web API and I try to process them and register them in fingerprint reader and sqlite database eventually my application freezes.
Any help will be appreciated.

This log means that Garbage collector just released the memory. You are making a lot of allocations and this is the reason why GC have to work frequently.
I recommend You to use Android Profiler (Android Studio 3.0) and try to overcome this problem: https://developer.android.com/studio/profile/memory-profiler.html
or past your code so that we can think about it together.

Android app: how can I use up memory, leaving only 20-100 MB

I'm working on a stress testing tool, one of designed scenario is to use up memory, and leave only a few mega for the app under test and others.
By searching internet about this topic, I learned that Android Dalvik vm limit program allocation in 16MB, 24MB, or 32MB. But I do realized some app can retain up to 80 MB memory. So is that idea reasonable? if so, how to achieve that goal.
thanks in advance,
Forrest

I would use one or several services to consume memory.
This article tells us that Leaving a service running when it’s not needed is one of the worst memory-management mistakes:
https://developer.android.com/training/articles/memory.html#Services
and this one tells us which process is killed last:
http://developer.android.com/guide/components/processes-and-threads.html#Lifecycle
In addition, I would use a foreground activity to cause killing the app under test (and see if the data survive): when the memory is already allocated to services, a foreground activity would cause killing of the background activities.
Android is a Linux, so you can use stuff like /proc/$PID/maps (see here).
It's interesting to know what you will use, so please answer your own question after you solve the problem.

thanks following up with me. Now I believe I get an answer to this question.
Generally speaking, we cannot rely on one app/service to use up the whole system RAM. Andoid app runs in Dalvik vm and there's an upper limit for each application or service. It's also known as maximum heap size limit. Different phones has different limit heap size:
HUAWEI U9508: 256MB android 4.0.4
Meizu MX3: 192MB android 4.2.1* ll
We can get this heap size by code:
Runtime.getRuntime().maxMemory();
Android Service fall into this rule as well, the heap size limit is the same as normal app.
Initially, android os give the app a relatively small heap, when the app reach the capacity, memory manager will grow the heap size automatically. Later, if app reaches the heap size limit, you'll get OutOfMemoryError. See below log(copy to text editor for better reading):

Too many GC_FOR_ALLOC in logcat

while running logcat on my app's logs, I see lots of GC_FOR_ALLOCs and no GC_CONCURRENT messages. I know I have memory leak, but everywhere in stack and other sites, logcat messages has lots of GC_CONCURRENT messages, and few GC_FOR_ALLOC messages. I wanna know what am I doing wrong? Do I have any special case of memory leak in my app? what's the problem?
BTW: I know Eclipse MAT and I'm trying to fix memory leak using MAT. I just don't know why GC_FOR_ALLOC is called so frequent.
logcat:

This may be a problem in Android's heap implementation:
http://androidxref.com/4.4.4_r1/xref/dalvik/vm/alloc/Heap.cpp
See comment in tryMalloc:
There will be a lot of churn if someone allocates a bunch of big objects in a row,
and we hit the frag case each time. A full GC for each.

Android GC_concurrent pauses activity

I love garbage collector, and it does it work good. But the problem is I have too many objects in my activity because there are too many Hashmaps and arraylists and other objects. So when I switch to other activity this happens.

So the problem is Switching to other activity pauses the application for like 4 to 5 seconds and it looks like the app is going to do Unfortunately and then ohter activity starts. So what can I do to NOT pause the activity the app
What I have tried
1. Starting Activity in async task. (Displaying the progressbar when GC does the above work)
but the progress dialog also pauses.
2. Do the same with handler and thread.
above things did not help.
So How can I display a progress dialog when GC does its work and not pause the activity? I don't want to manually remove manually.

Is this normal GC behaviour from support.map.fragment?

I'm having some issues understanding the GC, and Maps V2. On Zoom (in / out) the GC kicks in constantly cleaning up, making the application hang for half a second in the mapview.
If I remove the mapview from the application everything runs fine, but as soon as I add the mapview GC kicks brutal in (On create, and on zoom in /out).
I'm using the supportv4.support.map.fragment. I dont know if I should include layout and code? As this is many classes, and a whole lot of code for a general question.
Would you say this is my fault / Most likely implemented maps wrong? Or caused a memory leak?
Or is this normal behavior? I run the app on my Xperia Z, and it works "ok", but if I try it on my S2 it's a nightmare.
