Android :: Time Code Execution ?
Jun 27, 2010
What is the easiest to time execution in Android?
I have looked around a bit and I found TimingLogger on the Android SDK, and instructions here. It looks very convenient. But I can't get it work. This is my code:
CODE:................
It's is supposed to dump the times in in LogCat. But I can't see nothing.. I What am I doing wrong? Eclipse doesn't show any varnings. I guess it has something with verbose ouput, but I have set LogCat to show Verbose.

I am using Eclipse for Android development and Latest version of Android SDK (Running XP, 2Gb Ram)
1. when run clicked, previously executed emulator appears first then emulator default screen appears, only last current actual output appears
2. when clicked to close takes too much time (2 mns) for the emulator to disapper
3. in short execution time exceeds development/coding time in the testing process
is anyway to reduce such execution time

I'm currently working on an app for the android os that requires to fetch data from a remote server from time to time. as this "update" should be carried out even when the actual frontend app is not running, i implemented a remote service that is started on system boot. now i need to schedule a timer to start the update. is the "Timer"-class the right one for this job? and if "yes": what is the difference between a "normal" Timer() and one started as a "daemon" by Timer(true)?

I want to display the status of the activity execution on the screen using the TextView while activity is executing. I am appending the String messages at different stages of execution in the TextView, which is defined in the Layout main.xml (e.g. TextView.append("Server started..").
For e.g. I am running socket communication application in which my android application is the server and it is receiving the messages from the local desktop. So in this application I want to show "Server started.." message when socket server on android started , then a messge "waiting for message.." and then "message receivied.." when message received by android server.All 3 steps are the part of a single activity.
But in my case, I am getting all 3 messages at a time after activity execution completed. Is there any API available, using which I can show the status during the execution also.

I have a ImageView acting as a top banner on top of a webview. The image of this banner is created in execution time dependending on the resolution of the device. The height of the banner is always the same for each resolution. The only thing that changes is the width, which changes according to the orientation. But, since the width changes and the height doesn't, I end up having sort of 2 images with different proportion. And this is way the scale down/up won't work out for me.
Another problem is that everytime the user rotates the screen, the banner image is created again but Android seems not to update the image and thus I have a banner missing part of it.
I thought about having a real big image that will fit for both landscape and portrait orientation. But this seems not to be a good idea since Android keeps resizing the image everytime so it will fit on the space of the ImageView.
I'm running out of ideas here. Can someone suggest something?

Now, I am trying to verify the JNI in Android Java platform. I am using HTC G1 phone. I write a simple .c file to make a hello.so and a simple hello.java file to load the library. My story is like below:
1. create hellolib.c file and compiled to a hellolib.so create a folder in create a hellolib.c file hellolib.c, it really nothing just a function return;
*#include <jni.h>*
*#define .LOG_TAG "TestLib"*
*#undef LOG*
*#include <utils/Log.h>*
*JNIEXPORT void JNICALL java_com_testHelloLib_PrintHello(JNIEnv
* env, jobject jobj)*
*{* *LOGD("hello android LIB");* *}*
I compiled the hellolib.c to .so by changing the android.mk:
*LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS)*
*LOCAL_SRC_FILES := hellolib.c*
*LOCAL_C_INCLUDES := $(JNI_H_INCLUDE)*
*LOCAL_SHARED_LIBRARIES := libutils
LOCAL_PRELINK_MODULE := false*
*LOCAL_MODULE := libhello *
*include $(BUILD_SHARED_LIBRARY)
* push the libhello.so to /system/lib
2. create a .java file.
*public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
native_test.add_xx(1, 2) ;* * }* * }

I'm trying to put a timer in my code to determine the amount of time it takes to execute a block of code.
I've tried googling up some ideas, but they are all related to scheduling tasks, which is not what I want.
I want to, perhaps, place a time stamp in different parts of my code. How can I do this?

I have an Android code base which uses APIs with settings to get different data for several apps. All apps use the same code base but with one or two design tweaks. So how do I re-use the main code base without having to copy the whole Android project each time?
iPhone uses multiple targets in the same project which works well. If android cant do this do I need to compile binaries of the code base in one project and then import into each new app project? If so how? I'm using Eclipse and am an intermediate Java developer.

I'm currently learning android and java, and I am having some issues with importing a java file.
I am working with the time and date example in the android api demos, and I want to put all the code relating to creating the time and date dialogs setting the values etc into a separate java file, and in my main java file run when the application starts, just declare the buttons and onclick events.
What is the best way to do this? Do I need to put all the code inside a class(that extends activity) or method? How do I use this inside my main class. Code...

My application has a MapView which shows a collection of items in a satellite view. I use the MapController's zoomToSpan() method to initialize the zoom level of MapView. I later discovered that the MapView was showing a blank white screen with grey X's (zoom'd too far, zoom out once and everything looks as expected) for the use case when the collection of item's locations were very close to each other.
So, I modified the code from this:
CODE:......
To this:

I saw on Internet some services that give you the possibility to test an Android app on the web: for example, Manymo launches an emulator on a remote server and give you the possibility to interact with it. AppSurfer let you test your Android app in an emulator-like environment. Pieceable Viewer is similar to AppSurfer but for iOS.
According to you, how these services are implemented?
Maybe there are some emulators running on a remote server on which run a vnc server, but looking at AppSurfer or PieceableViewer they looks too responsive for this implementation.

Occasionally I see thread execution hiccups on my Motorola Droid (currently running 2.1 but I saw it with 2.0.1, too). Normally my dummy thread (full tilt, foreground, not doing *anything* else) runs in about 5-6mS. However, I see a second hump around 13-14mS and stragglers anywhere out to 80mS (typically around 35mS, though). What is going on? Why is this scheduling so non-deterministically? What is the solution? I could deal with a couple mS slower if it would get rid of those stragglers that exist the whole way out to 50-80mS..................

I have an android app that repeatedly collects fingerprints from the wifi-networks that are around (for scientific reasons, not to invade anybodies privacy). Anyways, imagine I have a function that does this work and it's called scanWifi(). I initally wanted to start it like this:
ExecutorService mExecutor = Executors.newSingleThreadScheduledExecutor();
mExecutor.scheduleAtFixedRate(new Runnable() {
@Override
public void run() {
scanWifi();
}
}, 0, interval, TimeUnit.MILLISECONDS);
Sadly, this only works reliably when the phone is plugged in. If it's plugged out and lays there for a while, it doesn't run my scanWifi() function every minute. Sometimes there are gaps of several minutes between single calls to scanWifi(). I also tried doing the same thing using a Timer/TimerTask with similarly poor results. The only thing that seems to work more or less reliable until now is to post it to a handler and call it repeatedly, like this:
Handler h = new Handler();
Runnable r = new Runnable() {
@Override
public void run() {
if (!mIsStopped) {
scanWifi();
h.postDelayed(this, mInterval);
}
}
};
h.post(r);
Why is that the case? Is the CPU sleeping and thus misses the scheduled execution? I hold a partial wakelock in my app.
