Current AndroidStudio sample fails on phone due to runtime native library link error. Why?

Its on an HTC Aria, running 2.2 (API 8)
https://en.wikipedia.org/wiki/HTC_Aria
The aria is an armv6 device that supports opengles 2
If you open up the latest Android Studio (im working on windows 7), then import the HelloGL2 sample, then simply try to run it on the above device, it will fail as soon as it tries to make a call into the native library.
Here is the log:

This sample works on the 3 other devices i've tried (Galaxy s5, Galaxy J1, Nexus s)
The line: 'Unable to dlopen(/data/data/com.android.gl2jni/lib/libgl2jni.so): Cannot load library: link_image[1995]: failed to link libgl2jni.so' is probably key. I tried loading the library explicitly using system.loadlibrary, but the same problem happens on that call.
I think it might be something to do with the processor being armv6?
The sample is configured to do 'armeabi' though.

RuntimeException using Camera.open()

This is likely an advanced question since I have a a fair bit of experience with developing camera apps for Android and have the basics right. On some phones, when calling
Camera.open(0);
I get a RuntimeException. My camera app works on most phones (1000+ device types of Android) but fails on a few (about 50+ device types). It also appears to be inconsistent across devices meaning the app will always work or fail on the same model of the device. E.g. the app works on some Galaxy S2's but fails on other S2's.
I have couple of logcats:

<br/>
I have tried a lot of things but I just cannot figure out what the problem is. This line of code is one of the first lines to execute (Camera.open()) so it is unlikely the error is in my code. Any insight as to why this line fails on some cameras will be very helpful.
If it is relevant, I am opening the camera from a service. I can post any information that is needed to diagnose this problem. Thanks.

do you include camera permissions and features in your app?
if yes, maybe the camera is in use in another app.
from android developers:
"Throws RuntimeException if opening the camera fails (for example, if the camera is in use by another process or device policy manager has disabled the camera)."

Memory error in Android after capturing images

In my Android application I'm trying to capture three images and upload this three images. I'm capturing two images one by one no problem but when I capture third images the application crashes with error:

How can I solve the error like this?

libs suddenly won't load in dynamic linker (NDK)

I've been developing an NDK app for quite some time and it's been working well. However, today the app randomly decided to not start anymore, after I compiled it after making some nominal change. It's caused by a cryptic problem with loading the app's main library. Here's some log output:
08-11 18:38:11.220 D/dalvikvm( 1237): Added shared lib /mnt/asec/com.audia.rta-1/lib/libqtandroid.so 0x40513bd8

According to some Google results, _ZNSaIcEC1Ev is part of libstdc++. I've checked, and it gets linked in the build process, and g++ is being used for linking.
Oddly enough, reverting to an older apk of the app fixes the problem, but compiling an old revision and installing that doesn't fix the problem. Everything in my build system is checked into version control, and I've done several clean builds. All my builds were working today and then they just stopped working. I didn't upgrade or install anything; it happened while I was in the middle of testing new code. What happened?
Update: Building from a freshly checked out copy doesn't fix the problem.
Update 2: Is there any way I can track down the link to that symbol, maybe with objdump? Maybe this could provide some clues.

I ended up compiling everything with a fresh NDK install, and it worked. It's as if the old one was corrupted somehow, though I have no idea how.
It was also an upgrade from r5b to r6, so maybe it's related to the NDK version.

Launch market place with id of an application that doesn't exist in the android market place

I am creating an application that checks the installation of a package and then launches the market-place with its id.
When I try to launch market place with id of an application say com.mybrowser.android by throwing an intent android.intent.action.VIEW with url: market://details?id=com.mybrowser.android, the market place application does launches but crashes after launch.
Note: the application com.mybrowser.android doesn't exists in the market-place.
MyApplication is my application.

Any ideas?

I am having similar problem when trying to open a detail page in Market app using "market://details?id=pname:org.rabold.android.puzzleblox" URL from an application.
I can create a shortcut using AnyCut like this:
action: android.intent.action.VIEW
data: market://details?id=pname:org.rabold.android.puzzleblox
type:
then it works fine.
However, if I create an Android application with a button to launch Market with the same Uri as above, then I get an error in Market app like this: "Attention: A server error has occurred. Retry, or cancel and return to the previous screen."
The code of my button's listener looks like this:
okButton = (Button) findViewById(R.id.okButton);
okButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_VIEW,
Uri.parse("market://details?id=pname:org.rabold.android.puzzleblox"));
//Uri.parse("market://search?q=pname:org.rabold.android.puzzleblox"));
startActivity(intent);
}
});
Note in the above code, if I use 'search' instead of 'details' then it works. I'd like to use 'details' instead of 'search' because I know that my app will be available on Market when it's done. Thanks.

Update!:
Do not use "pname:"
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("market://details?id=com.example.android"));
startActivity(intent);
Works perfectly.

thnx Daniel, I can confirm that your solution is working fine on device.
#TPham: please try with correct url (append id only),
passing correct id also working fine, see example below;
static final String APP_MARKET_URL = "market://details?id=com.wareninja.android.fotolicke";
Intent intent = new Intent( Intent.ACTION_VIEW,
Uri.parse(APP_MARKET_URL));
startActivity(intent);

instead of launching with the exact ID, you can try doing it by searching by the package.
Intent intent = new Intent( Intent.ACTION_VIEW,
Uri.parse("market://search?q=pname:com.package.package2.package3"));
startActivity(intent);
