I would like to inject code in an android application at runtime. I have tried to use dx tool to generate a dexfile in the sdcard but when i want to instantiate, it fails. Are there any tools to inject code generating new dalvik bytecode? I am studying some libraries, aspecjt or guise for android. Is it better to work with a script language?

This question has been asked(and answered) many times about dynamically generating and loading java bytecodes at runtime into a running Dalvik VM, but is there any way to load dex files/bytecodes into an app at runtime?

1. generate a Java stack trace in Android. In J2SE, we use to use something like this - send a signal to the Java Virtual Machine; the Java Virtual Machine generates a stack trace for you; or we can also use debugging tools or Java API calls.

The use case that I have to emulate is to inject random keypresses. I have observed it that it is possible using adb shell command "input". Can someone point me to the source code in the android build tree, so that I can accordingly implement the same in our test app.

One great example of what I am thinking of doing is what Google Android sdk does: they have an R class generated automatically from the resources. Every time a resource file is saved in Eclipse R class is automatically regenerated.
UPDATE: Example:
In the text (xml or json file) I have the following:
<tags>
<tag id="ALPHA">
<description>The first alpha tag.</description>
<value>231232</value> </tag> <tag id="BETA">
<description>This is the beta tag.</description>
<value>231232</value> </tag>
Then in my generated java class, say R I would have something like:
R.tags.ids.ALPHA //refers to an enum value for example
R.tags.values.ALPHA //refers to final int with avlue 231232
R.tags.descriptions.ALPHA //refers to the String with description
I'm not sure what's wrong here, all i want to do is randomly grab an item from my array. Which is just like a random sentence. Then generate another once the button is pressed. All my code looks good to me but it's causing a crash when i hit the button. any ideas?

View 2 Replies View RelatedI have developed an app for my customer at API level 5 (2.0) and above, and set my minSDKVersion as 5. Now my customer would like to know if it can be made backward compatible with API level 4 (1.6). I have a vague idea which areas might not immediately be compatible without doing some conditional code, but...
Does anyone know if there are any tools that can do a simple analysis of my code and list for me any API calls I have that and their API levels (preferably sorted, though I can do this if I can export the info)?
This seems like a very useful tool if someone has it? (I'm not expecting a full static code analysis, just API levels of all API calls in a project)...
1. I have a c lib which will send & receive multicast package, if I lauch it in native ap, everything is OK, but if lauched through jni ,so it run in dalvik env, it can not receive multicast, i think is may be disabled by dalvik, is there any permission can enable this feature?
2. In this lib i will make some callback of function in dalvik class. according to tranditional method which can run under JDK1.5 & 1.6 as follow: (I make it under source code env not NDK)

I have researched extensively and am pretty sure this is not possible. I want to make a call and then inject DTMF when the far end answers. So 2 questions Is it possible ?
If not, how do I work to get it on the list of upcoming features to be provided on Android. I can say that this is possible on BlackBerry and Symbian, so Android is falling behind in this regard.
I would like to know whether there is a way to insert/inject a <string> element defined in an XML file into another <string> element, doing that just with XML.
For example I could have:
<string name="author">Francesco</string>`
and I am looking for something like:
<string name="about_application">Author: @string/author</string>`
so that getString(R.string.about_application) would result in "Author: Francesco".
I know that I could combine the two elements in Java code using String.format(string, formatArgs)like for example:
<string name="author">Francesco</string>
<string name="about_application">Author: %1$s</string>`
and then in code use
String.format(getString(R.string.about_application), getString(R.string.author))
but I would like to do it in XML directly. Can anyone suggest me a way to do it?
I'm looking into a solution that needs apps to be dynamically extensible. One way could be an extension language or scripting engine. I've seen the Android Scripting Environment, but this needs the actual C scripting engine (Python or Lua) running as a separate process. I would like the runtime to be a Java app itself, like JavaScript using Rhino (and not using a WebView). Another way is to download Java code dynamically. But, Android does not support jar downloading and dynamic classloading, since these bytecode class files are not used directly.

As far as I understand none of them I can use fully when I do coding for Dalvik:
JUnit -- android.jar has its own junit.jar and my assumption is you're supposed to use it, not the latest version from junit.org Mockito -- read this one http://code.google.com/p/mockito/issues/detail?id=57 EclEmma -- doesn't support Android JUnit tests
