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?
View 1 Replies View Relatedi'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?
View 3 Replies View RelatedI 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?
View 2 Replies View Relatedmy 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.

It has two inversion functions on one app.
Public person can get his/her own public web site on the phone and secret person can use only private file sharing directly on the phone without uploading.
Those who want two demands above will use whole functions.
What will you choose of those choices?

When ever we need to send an email in Android we will invoke registered email application using Intent.ACTION_SEND. like the below
Intent i = new Intent(Intent.ACTION_SEND);
startActivity(Intent.createChooser(i, "Send mail..."));
My doubt is why do we need to use Intent.createChooser in startActivity rather than using
startActivty(i).
Is there any specific reason of using Intent.createChooser()?
I'm reading the android source code, and wanna make orientation animation. I've found that when I rotate the screen, the code will be executed to public boolean setRotationUncheckedLocked(int rotation, int animFlags){}, in which there's a line startFreezingDisplayLocked(). If this method works, there's no animation when I rotate the screen. Thus, I wanna know whether Google forbid orientation animation on purpose, and if I wanna make an animation, whether just use stopFreezingDisplayLocked() instead? Thanks a lot.
View 6 Replies View RelatedI'm writing a JNI library for a game. I have java code that I want to replace with functions from the library. Is it true that most of the devices out there are compatible with my code if I compile it for the default arm processor, or will I find that there are many devices out there that my library won't run on? What I'm asking is, should I maintain java code that does the same thing as my jni library for compatibility purposes, or is it safe to have jni libraries alone? How large is the group of devices that cannot use the libraries I write? Where are there stats regarding what population is using processors other than the arm processors?

View 1 Replies View RelatedI want to capture Intents with a specific Uri pattern that uses the http scheme. I DO NOT want the chooser dialog to pop up. The Android API advertises filtering of intents based on pattern matching of the path part of the Uri:http://developer.android.com /guide/topics /manifest/data-element.html However, when I try to specify a pattern for my path other than ".*" (which pops up the chooser, which I'm trying to avoid), it doesn't work, and the browser automatically handles the Intent. So, my question is, what is the purpose of the pathPattern/pathPrefix if, for the http scheme, it either auto resolves to the browser, or pops up the chooser anyways?

If this is intentional, what's the purpose of having the LED flash for only a limited amount of time?

I'm writing an application which connects to a back office site. The backoffice site contains a whole slew of JavaScript functions, at least 100 times the average site. Unfortunately it does not load them, and causes much of the functionality to not work properly. So I am running a test. I put a page out on my server which loads the FireBugLite javascript text. Its a lot of javascript and perfect to test and see if the Android WebView will load it. The WebView loads nothing, but the browser loads the Firebug Icon. What on earth would make the difference, why can it run in the browser and not in my WebView? Any suggestions.
More background information, in order to get the stinking backoffice application available on a Droid (or any other platform except windows) I needed to trick the bakcoffice application to believe what's accessing the website is Internet Explorer. I do this by modifying the WebView User Agent.Also for this application I've slimmed my landing page, so I could give you the source to offer me aid. package ksc.myKMB;
