Android :: Show Method Definition - Eclipse Recognizes Warning On Method
Nov 22, 2010
In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition. If I try hitting F3, I get a "The Jar of this class file belongs to container "Android 1.6" How do I show the definition of the method I am using when there is a warning?

public class MyClass extends ActivityGroup {
@Override
public void onBackPressed() {
// do something
return;

I have written my input method on lines of LatinIME. My IME "MyIME" has a service and an activity similar to LatinIME.
Installing it to emulator via eclipse does not seem to work and hence I have tried the following approaches.
MY GOAL: ~~~~~~~~ All I need as the first step to know that I am heading in the correct direction is that I should be able to see "My IME" as one of the available input methods. For example, on any EditText, when I "long click & release", the Input Method menu that pops up must also show "My IME" as one of the available input methods.
However so far the pop-up only shows "Android keyboard" (LatinIME). Hence I tried the following approaches.
Approach-1: =========== I checked out the andorid source code and built & ran it successfully to make sure I got the build process right. I created my project in ~/mydroid/packages/inputmethods/MyIME. It has the package structure 'com.android.inputmethod.myime' (to be in line with Android's package structure, I am not sure if this is required).
I ran a build using "make". Make succeed in compiling MyIME, just like LatinIME and all the android tools were also created. However looking at the build output, LatinIME was installed into /system/app/ LatinIME.apk while MyIME was not installed at all.
Question with respect to approach-1: ------------------------------------ 1. How to get the build process to install MyIME into /system/app as MyIME.apk?
Since install did not happen via the build process, I started the newly built emulator (and newly built ddms to watch logs) and used follownig install approaches:
Approach-2: =========== I ran 'ant debug' to get MyIMESettings-debug.apk. Then I ran 'adb install MyIMESettings-debug.apk'. The attempt failed with the message "Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]". Hence I tried the approach-3.
Question with respect to approach-2: ------------------------------------ 2. Why did the install fail when the project was built using 'ant debug'? Is it some thing to do with debug signature?
Approach-3: =========== The build process had created an APK file but hadn't installed it (/ mydroid/out/target/product/generic/obj/APPS/MyIME_intermediates/ package.apk) I renamed that package.apk to MyIME.apk and installed it using "adb install MyIME.apk". The install succeed. However, the adb install put my APK under /data/app with the name "com.android.inputmethod.myime.apk" instead with name MyIME.apk
Question with respect to approach-3: ------------------------------------ 3. Is there any way to get "adb install MyIME.apk" to install into / system/app folder?
Again, what I am trying to achieve is mentioned under "MY GOAL".

I have code in my activity's onCreate that sets an onItemClick listener. when it fires I try to show a ProgressDialog that will be up until a subsequent thread "Thread" does it's processing. Strangely to me, the progress dialog never shows until *after* the thread.run() processing is complete. Almost like it's blocking. Am I doing something wrong? this is true even if the run method of doCurrentLocation doesn't do anything.

Since previous releases of android SDK (I think since version 0.9), I have a warning when I run a aplication from Eclipse.
"Warning once: This application, or a library it uses, is using NSQuickDrawView, which has been deprecated. Apps should cease use of QuickDraw and move to Quartz."
How I can solve this? I am running Eclipse 3.4 (Ganymede) in Mac OS X 10.5.6.

Is there any method to get one view by name rather than it's ID? Because we are composing a common lib, and it's not able for us to know the Resource ID at this time. So is there any method to get one view by name, not by findViewById?

Is there any method that listens for map moves or zoom changes? I know there is a mapMoved() method in the map listener interface for the nutiteq map (I'm using google maps though) so I'm wondering if there is anything similar for google maps, or if not, if there is someway to listen for getMapCenter() changes.

I am trying to write an app that will only run if the phone has a camera flash (i.e. not on my HTC Hero but on a HTC EVO 4G or Samsung Epic 4G, etc...). I found a code sample that will set the flash mode (and should work) but after modifying it to get the flash mode I am told that no phone has a flash when I run it even if they do. My code is as follows, I'd appreciate any help on figuring out what I did wrong since it looks correct to me.

You need a reference to the class that contains the method you want to call. To access the method homepage() inside the eSkyGuide from the class Weather, you need an instance of the eSkyGuide class inside the instance of the Weather class.

Is the onUpgrade method of SQLiteOpenHelper ever called? If so, when is it called and by what? Or if it is not called by developers, then why is it there? What should be done in the method I have seen examples where it drops all the tables, but then a comment says that dropping all the tables is NOT what you should do.

I am new to Android development and have been following the tutorials available on the Android website. I am currently on the section of tutorials for Views, specifically the one for Grid Views: Hello, Grid View Tutorial.I am having trouble understanding how views are made through an adapter. I understand that you must override the getView() method in your adapter class and in this method is where you define how your Views are set up. What I don't understand is where does getView() actually get called? Perhaps I've got the wrong kind of mentality here, but in the code below (the Grid View tutorial) I don't see any calls to getView() (or any other things used in the adapter class such as getCount()).
