I wrote a JAVA application with native methods, and trigger encoding program in native methods. That makes two processes, one is application process, another is encoding process.I would like to know if there is a way to get encoded data from encoding program and pass them to JAVA application.

I would like to share a cache file across activities, which are running in different processes but in a same application.So, is there any way to make it thread safe (probably not "thread safe", should we call it "activities safe" or "process safe" ?
View 2 Replies View RelatedI want to share data between 2 applications. the idea is both applications can write and read the SAME data and there is no dependency which one of the apps is installed or first created the data. I have 2 version of the same app: regular and premium and I don't know which of them will be first installed and both of them can change it.I tried to use ContentProvider but the problem is that only the first app can create the Provider and when it is uninstalled it deletes that custom Provider. I want the Content to be kept for the second app. Also, I tried to use Settings.System which keeps the data regardless if the application is installed or not but I don't want to use the permission for that (it is very problematic from user perspective). BTW, it seems that I can change ANY of the Settings.System which is not secured from Android OS perspective - but this is a subject for other post.

View 5 Replies View RelatedI have an app that creates a new data entry in a sqlite db with several columns. I would like to have a simple share button on the final activity so they can share the results (or even a simple text field) with apps that accept it (email, mms, twitter, etc..). I did some reading on ContentProviders but the more I read, the more I'm thinking i'm heading down the wrong path.
View 2 Replies View RelatedI've added the intent-filter. And when I tap "share" in the Gallery, it will launch my activity.
<intent-filter>
<action
android:name="android.intent.action.SEND" />
<category
android:name="android.intent.category.DEFAULT" />
<data
android:mimeType="image/*" />
</intent-filter>
But I don't know how to get the correct data from the current intent.
I want to create an app that contains a Service S and an Activity A. The Service S is responsible for preprocessing, such as preparing the data shown on the UI of the Activity A, before the Activity A gets invoked.I want to be able to invoke the Service S from outside the package, say from another Android app's Activity class B, do the preprocessing, and then when the data is ready, invoke Activity A. What is the best way to share data between the Service S and Activity A?How can the external activity B communicate with the Service S to determine if it has completed with all its preprocessing, and the Activity A is ready to be invoked?
View 1 Replies View RelatedI have a free app in the market and use the data directory of the app to store some files. Now I think about offering a paid (donate) version of the app, so that people who want to pay a few pennys will be able to do so. But AFAIK the new (paid) app needs a new name, so I won't be able to use the stored data of the free version. That means, that existing users would have to re-enter a lot of personal settings - which probably would be a no-no for a lot of users. So my question: Is there a smart way to have a free and a paid version in the market, where the later installed payed version can use the data of the free version? I thought about using the SD-card for data storage, but there might be devices without any SD-card...
View 5 Replies View RelatedSuppose you have an app with a lite version and a full version. The app stores some user data in SharedPreferences, and some data in a SQL database. If a user tests the app for a few days, generating data all the time, and then decides to switch to the paid version, how do you copy or share the data between the two? Some code examples would be appreciated - but for some reason I have a feeling this is much, much more complex than I hope.

View 3 Replies View RelatedIt would be nice if StackOverflow had a section where we could post tutorials like mine so that I can answer literally hundreds of questions that have been asked here with a single blow. See... every day I read questions about how to pass complex objects between activities, how to save state so that your app can resume after orientation change, how to update listviews when the data changes, etc, etc. Here is the second part of a tutorial series I posted on my blog... I hope that you actually read it... because I haven't seen any examples like it anywhere... and it has changed how I think about developing for Android across the board. The question is... is there a downside or negative affect of developing like this?

I'm looking for a solution to connect one android phone to another over bluetooth to share voice and maybe data service. What I want to do is use my old Dell Streak as a GPS/media player in my car without having service to it. I would like it to connect to my current phone so I can make call through it, like a headunit with hands free bluetooth calling. I'm not so much worried about data, though it would be a plus but I don't think Android supports connecting to ad-hoc networks. I can't seem to find any app that supports this, and I'm not seeing anywhere on the Android system where this is possible. I haven't owned a car stereo that supports bluetooth calling so I'm not sure what to look for.

View 4 Replies View RelatedTrying to make Tasker automatically open and populate Astrid todo's task edit fields the way that so many other apps can using the Share menu. With pretty much any app being able to do this using Share, I figured it wouldn't be too hard to make Tasker do the same, but I'm having trouble finding out how.
I'm using the beta of Tasker so Send Intent replaces the previous two intent actions. The fields available are Action, Category, Mime Type, Extra, Package, Class, and Target. Right now Package is set to com.timsu.astrid and Class to com.todoroo.astrid.activity.TaskEditActivity, which manages to open the task edit screen. That intent is however from the Astrid widget so I don't know if that's even the right thing to use if doing this via the Share ability.
Is there a better way then using titanium backup and manually doing this? Seems like a crazy tedious thing to do. I jump back and fourth between the two devices even on an hourly basis. one is my phone and the other is a tab.

View 49 Replies View RelatedI have an app which declares a BroadcastReceiver, the receiver gets the broadcast, does what it needs to, then ends ensuring that everything is tidied up as needed. When I examine the system through the DDMS view in Eclipse the process for the application is still running after the receiver has completed. I've even boiled it down to a simple test case which gets a shared preferences instance from the context, checks a random setting, and then exits, and, when run on the 1.5 emulator (which is the minimum supported OS level) the process is still hanging around.The reason this is an issue is memory usage (which shows under DDMS as around 2MB).I've had queries about why the application still uses up memory even when it's not doing anything, so, my question is; Is this behaviour normal, or have I missed something that would make the process exit?

View 3 Replies View RelatedWe were told that, as of Android 1.6, background processes were put in a Linux process scheduling class that limited how much CPU they would use. A few weeks ago, I ran a benchmark test that seemed to validate this claim.I have run more tests, and I am no longer confident in my earlier conclusion. I can get a background process to significantly impact the foreground process, more than would seem to be possible if the background process was, indeed, CPU-limited.

View 2 Replies View RelatedI have read all about having separate processes for different Application components, and how to use them.I am curious, what are some appropriate use cases for when an application should actually use separate processes?It seems to me, the main advantage to using separate processes is to make the different portions of your app more easily killable by the OS.
View 7 Replies View RelatedI've been trying to locate some excessive object creation to deal with hiccuping caused by the garbage collector (any word on upcoming improvements to this, btw?), and have discovered that DDMS is the tool for the job.I shut down eclipse and booted up DDMS, and it finds my device, but lists no processes running (no matter what I run).Initially, it did list the "powermanager" app that I had installed, so I assumed this was causing some kind of conflict and uninstalled it and rebooted my device.Now it simply lists no processes.

I have an application with a multi-instance activity. I would like each instance of the activity to appear in a new task and process. Any suggestions on how to do this? By manipulating the manifest I can cause all instances of the activity to appear in a specific task and
process, but I haven't found any way to cause each instance to appear in a different task and process.(The requirement to have different tasks is that we want each instance of the activity to appear separately in the task list; the requirement for different processes is that each instance of the activity is backed by a chunk of native code with global state. We can't change either of these.)

In my application , i have an option to capture the hprof dump. I used
android.os.Debug.dumpHprofData (String fileName)
Initially i though the hprof data generated by the method above is for the entire device , which is not so . The hprof data generated is only for my process.
Now i am trying to generate hprof data for other process as well. I need to get the Hprof dump for all the running processes from application code.
from adb shell i tried "kill -10 <pid>" , This command will generate the hprof file for the corresponding process in the data/misc folder.
Now the problem is this command is working perfectly from the adb shell prompt , but i am not able to embed the command to mycode.
My code is like
Runtime.getRuntime().exec("chmod 777 /data/misc") Runtime.getRunTime().exec("kill -10 <pid>")
No exceptions are thrown , but somehow it is not working. The same code above is capturing Hprof dump for my process, when i give my process ID.
I tried with "android.os.Process.sendSignal (int pid, android.os.Process.SIGNAL_USR1) ;" also.Getting the same problem.It is capturing Hprof dump for my process. For other processes it is not working.
Do we need to have any special permission to kill other process from our process ? Or is it a built issue ? can you please suggest some possible way to get Hprof dump for other processes from application code?.
