EGL_BAD_ALLOC error

[EgonOlsen]

You need another model with more vertices then. You actually can't bend anything but a vertex. If there's no additional vertex between point A and B, the connection between them will always be a line.

[AeroShark333]

Hmm okay...

Another problem (offtopic again, sorry):

I sometimes get this crashreport, but I don't know why most people don't get it...:

This error occured for my users on:
Android 4.4: 5x
Android 4.3: 1x
Android 2.3.x: 9x

Fragment shader:

Code Select Expand

precision highp float;

uniform sampler2D textureUnit0;

varying vec2 texCoord;
varying vec4 vertexColor;

void main() {
gl_FragColor= texture2D(textureUnit0, texCoord) * vertexColor;
        if (gl_FragColor.a<0.5) {
           discard;
        }
}

Any help would be welcome! ^.^

Cheers,

Hard to tell. It can't be the shader itself, because i don't see anything in there that can fail on any current device. Is this the complete log output? Nothing is printed out before this?

[AeroShark333]

Yes this is the complete log output

[EgonOlsen]

How do you load the shader?

[AeroShark333]

GLSLShader loader:

Code Select Expand

GLSLShader shader = new GLSLShader(getStringFromFile(R.raw.alphatest_vs),
getStringFromFile(R.raw.alphatest_fs));

//apply to all objects
iH = new InnerHead(shader);
oH = new OuterHead(shader);

Textfile loader:

Code Select Expand

private String getStringFromFile(int id) {
final InputStream stream = getResources().openRawResource(id);
final BufferedReader reader = new BufferedReader(new InputStreamReader(
stream));
String result = "";
try {
String line;
while ((line=reader.readLine()) != null) {
result += line + "\n";
}
} catch (final IOException e) {
e.printStackTrace();
}
return result;
}

[EgonOlsen]

Try to replace your printStackTrace with throwing a new RuntimeException that wraps the IOException. Maybe the problem isn't the shader or the driver but the loading itself. With your code, this will remain more or less unnoticed. And don't forget to close the stream. Your current code doesn't do this. It's good practice IMHO to do this in a finally-block.

[AeroShark333]

Something like this?:

Code Select Expand

private String getStringFromFile(final int id) {
final InputStream stream1 = getResources().openRawResource(id);
final BufferedReader reader = new BufferedReader(
new InputStreamReader(stream1));
String result = "";
try {
String line;
while ((line = reader.readLine()) != null) {
result += line + "\n";
}
} catch (final IOException e1) {
final InputStream stream2 = getResources().openRawResource(id);
result = Loader
.loadTextFile(stream2);
try {
stream2.close();
} catch (IOException e2) {
// Doesn't matter
e2.printStackTrace();
}
if (result == "" || result == null) {
throw new RuntimeException(
"Could not get the String from the Resources");
} else {
return result;
}
} finally {
try {
stream1.close();
reader.close();
} catch (IOException e3) {
// Doesn't matter
e3.printStackTrace();
}
}
return result;
}

One problem is that this error does not show up a lot in the Google Play Store Developers Console really... Which makes it harder for me to judge whether the bug/crash is fixed or not.

[EgonOlsen]

No, not quite like that. It's better to use the RuntimeException constructor that takes the source exception as an additional parameter. The way you have it now only tells you that it didn't work out but hides the actual cause.

[AeroShark333]

So basically:

Code Select Expand

throw new RuntimeException(
"Could not get the String from the Resources", e1);

[EgonOlsen]

Yes, something like that.

[AeroShark333]

So I got a new stacktrace...

EDIT:
Some side information:
- Crash happened on a Android 2.3.3 - 2.3.7 (Device 'name': h712a)
- The version of Skin Viewer 3D he used, does have the new shader loader.
- This stacktrace is new, I have not seen this one before... However, it sort of looks the same as the previous stacktrace... But somewhy FrameBuffer is involved this time? o.O
- Only one user (of the 82165 users (where 13948 active)) reported the crash with this stacktrace. The previous one was reported 9 times. (different users too)

[EgonOlsen]

A complete log output isn't available? I would guess that this is either a driver issue (I was unable to find an Android device named "h712a"...only an older Envision monitor) or some problem with the gl context being destroyed or becoming invalid right after it's creation for some reason. Without a full log output, this is very hard to tell...

[AeroShark333]

No sorry, this is all I got...

[EgonOlsen]

...than it's pretty hard to find the problem without the device that has it. There exist several frameworks that allow for better, more detailed feedback in case of an error. Maybe that's an option...
