Android :: Getting Packages From PackageManager
Oct 10, 2010
I'm writing an app, that has a somewhat modular system. It has a core app, and some apps, that consist of a single Service, that implements the desired interface. I followed the guide to create the IPC communication. But now I need to get all the services, installed on the system, that my core app can work with. How do I do this? I mean, is there any way to mark my Service apps with some kind of a tag, and then filter results, presented by the PackageManager#getInstalledPackages() based on that tag value? What's the common practice of doing so?

i'm currently trying to specifically target ARMv7 custom hardware and I'm facing issues when trying to install the APK. When I try doing "adb install app.apk" Logcat informs me that: W/PackageManager( 1062): Native ABI mismatch from package file And does not install the APK. With searching I was able to trace down that the problem might have something to do with the architectures not matching on the APK and the platform. Is this it? How does the PackageManager find out the architecture from the APK file? I'm guessing it's not trying to execute the binary or anything, it just checks the files meta data? If so, is there a place in the APK where this information is located? Or am I completely hitting blank here and I should look somewhere else?

I want to use the SDK (PackageManager API) and dump all packages, their activities and the intent filters the activities use. So far navigating from the Context -> PackageManager -> ActivityInfo is easy. I am stuck trying to figure out how to retrieve the mappings from Activity -> Intent-Filter. Looks like from what i could tell from the SDK documentation, i can obtain the ResolveInfo (if i know the Intent). But how do i retrieve Activity to Intent-Filter mapping?

my application caches static resources in its /assets directory and implements a content provider to provide them to a WebView on request. i kinda have to drive around the houses a bit because it seems i can't get a linear file descriptor on an asset, i get "this resource is zipped" or somesuch, don't know why that's a problem. the content provider just caches the asset in /sdcard and then returns a file descriptor off that. this has been mostly working fine, but i've started seeing errors from the PackageManager. nothing's changed on my end, the assets are still there, etc. the actual error i'm getting is -ndroid.content.pm.PackageManager$NameNotFoundException: ComponentInfo{package/activity} (where "package" is the name of the package, etc) can i get anything wrong with this stuff? caching javascript and css stuff in the apk has been a big performance win.

I am running into a very strange situation when using the PackageManager.getInstalledPackages() method. The first time I launch my activity I get a valid list of all the installed packages. But the second time I launch my activity I get an empty list... What could possibly be causing this?
I am using this code to get the list:
CODE:...........
I am building against the 1.6 SDK with compatibility for 1.5+

I've been trying to modify the native android applications downloaded from the android source repo at github. But I noticed that after creating Eclipse projects from some apps, like the Launcher, there are missing imports, variables that are not declared anywhere else, etc... After my initial research, I noticed that some of the libs that are native, are compiled at runtime and registered in the dalvik VM as java libs and by having done this the system finds these as already present libs, the same goes for the "phantom" variables. But I don't understand how does a developer open such a project in any java ide, and compile it. So what do Google developers use to work on android apps? I don't believe it's eclipse, since I am not sure you can make eclipse use runtime imports, and runtime variables. And I am almost certain that they do not write code in notepad.

I am including a class in my app that another developer has made freely available. His class has a different package. Will this cause any issues on Android, the market, etc? Does every single class in the app need to be my own package?

if this is a silly question, am sorry about that. I was wondering if its possible to design android icons using a 3d modelling package like blender? i know i have to stick to the guidelines documented already, but was just wondering if anyone had come across or done something similar? Its that little part of the icons(launchers) being able to have a slight perspective and looking through the requirements to design icons it seems i might be a lot faster using a 3d modelling package and then following part of the icons template guide(based from my requirement though!).

I have seen several applications that are free, but allow for add on packages to be installed. Gang Wars sells Respect Points Mafia sells Favors Dungeon Quest sells Gems The central game is a free app, but you purchase these add on apps for in-game benefit. Has anyone purchased one of these add on apps? What is the experience like? Do you have to leave the add on installed on your phone? How does this work technically? Do you think they set shared preferences? How would you handle the 24 hour uninstall rule? I am considering releasing a free game with 10 levels, but offering a full set of levels (say 25) as a separate paid app. I'm looking for the best way to accomplish this and thought the above might have some bearing.

I want to display all the installed packages to user. Below is the code snippet I used but not sure why it is not working.
int flags=0; PackageManager pack = null; List<PackageInfo> packInfo= pack.getInstalledPackages(flags); CharSequence[] items = new CharSequence[packInfo.size()];
Vector <Process>allProcesses = new Vector <Process>(); for (int i=0;i<packInfo.size();i++) { String packI = "Packages"+packInfo; Toast.makeText(this, packI, Toast.LENGTH_LONG).show();
}
I just to display the entire list of packages to user. Any idea what's the problem with the above code?

My app targets 1.5, and runs fine on my phone (1.6), but to support droid, I need the package android.telephony.cdma from 2.0. Targeting 2.0 excludes the current devices running my app (including my own G1), but as it is now, I can't support the Droid.

I'd like to access resources from other packages installed. Is there any better practice than using getResources() combined with createPackageContext()? Another question is how to use resources from other packages in methods like Notification(int icon, CharSequence tickerText, long when), where 1st argument is just resource id?

I need to import a couple of jars that where compiled under the full implementation of java. I know that Android doesn't use all the packages that java has to offer. My question is: Is it possible to import them without creating errors? Is there a tool that can convert jars to android jars? if so, can some examples be provided.

So today I had a bright idea to rename my packages, now my android application which I have schedule for release on Thursday is not working.
I am getting a similar error as follows:
Error: Activity class {org.me.androidapplication2/com.albertrosa.DEMO.MainActivity} does not exist.
I have modified the manifest to reflect the change:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.albertrosa.DEMO"
android:versionCode="1"
android:versionName="1.0"
there is more to the manifest but this is all that I have changed. is there something I am missing or doing wrong. I am using netbeans to build this app.

I've created a service that is meant to communicated to an activity using aidl's and callback functions. I got it working just fine with my test activity in the same package. But I was wanting to expose this service to different activities running in a completely different .apk file. Is it possible to accomplish this? What does the separate package need to bind to my service and register the callbacks? Or am I going about this completely wrong and should I try a different method for conveying information back and forth between two packages.

First of all I'd like to mention I am very new to Java programming. This Android project is my first experience with Java. So for one task I need to strip HTML tags from a string. I was thinking about using this answer Removing HTML from a Java String to do this task. In order to do this I need to be able to import javax.swing.text.html.* and javax.swing.text.html.parser.*.
I went to the properties of my project and attempted to add this library to my project. I read that this was included in the rt.jar file which was located at /usr/lib/jvm/java-6-openjdk/jre/lib/rt.jar. I was able to use the imports but it seems like it added a million libraries I am not using. Will this negatively effect my application? What is the correct way to add just the one extension?
