I have a Marshmallow device. It has custom built SW.
I have seen the build.prop file. There I can perceive the Software version name comes from ro.custom.build.version
My question is - how can I get the "ro.custom.build.version" information programmatically in my application ?
I got the answer. It is very simple -
First, I created a function to read from SystemProperties.
public String getSystemProperty(String key) {
String value = null;
try {
value = (String) Class.forName("android.os.SystemProperties")
.getMethod("get", String.class).invoke(null, key);
} catch (Exception e) {
e.printStackTrace();
}
return value;
}
And then called the function with "ro.custom.build.version" as a key
getSystemProperty("ro.custom.build.version");
Special thanks to #sasikumar for giving me the hint
You have to do as below :
PackageInfo pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
String version = pInfo.versionName;
To get the Version code, Use as below :
int verCode = pInfo.versionCode;
Check android.os.Build.VERSION. You can use INCREMENTAL.
On Android, can we change the keyboard input language (English(US), Hindi, French, etc.) from Java/C++ or the terminal(like the imein /system/bin?
For those who said not possible here it is, it's very much possible but device needs to be rooted or your app needs to be system signed.
protected static void changekeyboard(String keyboardID, ContentResolver contentResolver)
{
String oldDefaultKeyboard = Secure.getString(contentResolver, "default_input_method");
Secure.putString(contentResolver, "enabled_input_methods", keyboardID);
Secure.putString(contentResolver, "default_input_method", keyboardID);
}
in keyboardID you need to pass the keyboardID of the keyboard you want to set.
or you may get the list of all keyboards and get the ID from there and pass it
Like this:
List<InputMethodInfo> InputMethods = ((InputMethodManager) getApplicationContext().getSystemService("input_method")).getInputMethodList();
this.keyboard_name = new ArrayList();
int numOfKeEyboards = InputMethods.size();
for (int i = 0; i < numOfKeEyboards; i++)
{
fullKeyboardName = ((InputMethodInfo) InputMethods.get(i)).toString();
keyboard_package = fullKeyboardName.substring(fullKeyboardName.indexOf("{") + 1, fullKeyboardName.indexOf("/"));
try
{
// by package name getting app name
inputKeyboardName = getPackageManager().getApplicationInfo(keyboard_package, 0).loadLabel(getPackageManager()).toString();
}
catch (NameNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
this.keyboard_name.add(inputKeyboardName);
}
I would need to List all the values in strings.xml (for a given locale),
basically get a dynamic list of all the strings in an application.
My purpose here is to list all strings of all apps inside my (duely rooted) phone in order to speed up translation work.
I have no problem accessing the AssetManager of other apps :
-To get the list of all apps I use :
List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
-To access the package manager I use :
PackageManager manager = getPackageManager();
Resources mApk1Resources = manager.getResourcesForApplication(pname);
AssetManager a = mApk1Resources.getAssets();
But I am not quite sure where to go from here.
Obviously this is not for production purpose, just for helping my customer's translation team (you know Chinese OEMs...), so jackhammer-dirty solutions are welcome :-P (reflection, dynamic foreign context, live dex loading, dynamite etc...)
Thanks !
Edit 1 : I already know B.A.R.T it doesn't suit my need I need to do it on a live phone (not a zipped ROM) like a "live translation checker app". In particular, I don't have immediate access to the app's source codes, because I have to check a large number of phones, some being few years old. I can spend the time to root all of them if needed, but not much more.
Edit 2 : I really need something that runs on a live phone without the need of a PC. I can't modify the source code of individual apps and I can't decompile the ROM or use external tools like B.A.R.T I need an all-Java solution.
I can see that: usually the string for application label will get the first id in the resource strings. (not found an official document on this yet)
So the plan is: get the id of the label of an app, increase the id each time to get the next resource string until we get the Resources.NotFoundException
try {
List<ApplicationInfo> apps = getPackageManager()
.getInstalledApplications(0);
for (ApplicationInfo appInfo : apps) {
Resources mApk1Resources = getPackageManager()
.getResourcesForApplication(appInfo.packageName);
int id = appInfo.labelRes;
try {
Log.e("Test", "*******************************************");
Log.e("Test", apps.get(0).packageName);
while (true) {
Log.e("Test",
"String resource: "
+ mApk1Resources.getString(id));
id++;
}
} catch (Resources.NotFoundException e) {
// Handle exception
}
}
} catch (NameNotFoundException e) {
// Handle exception
}
Seeing you said you accept "jackhammer-dirty solutions", give this a try:
In your Strings.xml, surround all your String values with a <string-array> tag, and all string tags inside change to item tags, like so (used simple find-and-replace to replace the tag names):
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="hello">Hello World!</string>
<string name="app_name">YourAppNAme</string>
<string-array name="yourTitle">
<item>item1</item> //used to be <string name"blabla">....
<item>item2</item>
<item>item3</item>
</string-array>
</resources>
In your xml Layout file, where you have your ListView, put:
<ListView
android:id=”#+id/yourListView”
android:layout_width=”match_parent”
android:layout_height=”wrap_content”
android:entries="#array/yourTitle"
/>
Now, your Activity where you have your List, just call the ListView which should already be populated with the items from the Strings.xml
Don't forget to revert the changes in Strings.xml once you are done (and backup is always a good idea)!

Hope this helps!
Since you've rooted the phone and have access to every APK in the phone, how about just decompile them and get to the strings that way, see tutorial here: http://www.miui-au.com/add-ons/apktool/
Ok, I guess I found it. Reflection did the trick !
Root was not even needed. Crazy to know that any apps on your phone can see all the other's ressources...
public void listAllStrings(){
List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
for(int i=0;i<packs.size();i++) {
PackageInfo p = packs.get(i);
String pname = p.packageName;
Resources packageResources=null;
Context packageContext=null;
try
{
packageResources = MainActivity.this.getPackageManager().getResourcesForApplication(pname);
packageContext = MainActivity.this.createPackageContext(pname, Context.CONTEXT_INCLUDE_CODE + Context.CONTEXT_IGNORE_SECURITY);
}
catch(NameNotFoundException excep)
{
// the package does not exist. move on to see if another exists.
Log.e(pname, "Package not found!");
}
Class<?> stringClass=null;
try
{
// using reflection to get the string class inside the R class of the package
stringClass = packageContext.getClassLoader().loadClass(pname + ".R$string");
}
catch (ClassNotFoundException excep1)
{
// Less chances that class won't be there.
Log.e(pname, "R.string not found!");
}
if(stringClass!=null){
//For every fields of the string class
for( Field stringID : stringClass.getFields() )
{
try
{
//We get the id
int id = stringID.getInt(stringClass);
//We get the string value itself
String xmlResourceLayout = packageResources.getString(id);
Log.v(pname, xmlResourceLayout);
}
catch (Exception excep)
{
Log.e(pname, "Can't access : "+stringID.getName());
continue;
}
}
}
}
}
Hope this can help others :-)
Edit : For some Apks, the R class is not at the root of the package, so I had to write a find-R function
String findR(Context packageContext){
try {
//First case, the R class is easy to find !
packageContext.getClassLoader().loadClass(packageContext.getPackageName() + ".R");
return packageContext.getPackageName() + ".R";
} catch (Exception e) {
//Second case, it is not at the root of the package, we will list all classes...
Log.v(packageContext.getPackageName(),"R not found... Continue searching !");
try {
final PackageManager pm = getApplicationContext().getPackageManager();
ApplicationInfo ai = pm.getApplicationInfo(packageContext.getPackageName(), 0);
DexFile dx = DexFile.loadDex(ai.sourceDir, File.createTempFile("opt", "dex",
getCacheDir()).getPath(), 0);
String pathToR=null;
// Search inside each and every class in the dex file
for(Enumeration<String> classNames = dx.entries(); classNames.hasMoreElements();) {
String className = classNames.nextElement();
//for every single class, we will see if one of the fields is called app_name
//Log.v(className, "Class detail : "+className);
if(className.contains("R$string")) pathToR=className;
}
if(pathToR==null) throw new ClassNotFoundException();
pathToR=pathToR.replaceAll("$string", "");
Log.v(packageContext.getPackageName(), "R FOUND ! "+packageContext.getPackageName());
return pathToR;
} catch (Exception exc) {
Log.e(packageContext.getPackageName(), "ERROR ! R NOT FOUND ...");
return null;
}
}
}
But it still doesn't work in every case. So I ended hijacking the apktools library so it could run live on a phone... (I used the jar from 1.5.2 http://code.google.com/p/android-apktool/downloads/detail?name=apktool1.5.2.tar.bz2&can=2&q=) Here is my hijacked class :

Lots of headaches for few Strings ;-)
I want some logic around a part of my code that can tell if I am using a certain theme. I would like to be able to tell if the current theme is equal to the theme with parent="Theme.Sherlock.NoActionBar".
I am wondering what the most efficient way to do this is as I can't figure out a simple way.
You can use the following code to get the name of the Theme and then compare it with the one you want to check.
public String returnThemeName()
{
PackageInfo packageInfo;
try
{
packageInfo = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_META_DATA);
int themeResId = packageInfo.applicationInfo.theme;
return getResources().getResourceEntryName(themeResId);
}
catch (NameNotFoundException e)
{
return null;
}
}
Is there a simple way to find the current version of my application from within it? I would like to add the version string to the about screen.
You should check this question.
I am doing it this way:
try {
String pkg = mContext.getPackageName();
mVersionNumber = mContext.getPackageManager().getPackageInfo(pkg, 0).versionName;
} catch (NameNotFoundException e) {
mVersionNumber = "?";
}
please try out this.
PackageInfo pInfo = getPackageManager().getPackageInfo(getPackageName(), 0);
version = pInfo.versionName;
