Hello,
I want to hook a method in com.android.commands.pm.PM but i fail to load this class (i get class not found exception)
I tried both using initZygote approach and handleLoadPackage approach, both with the same result..
what am i doing wrong?
Thanks!
Maybe @GermainZ can help?
Can you post the relevant Xposed code and exact error, please?
Hi,
Thanks.
Yes, here are my both tries...
Code:
public class XPm implements IXposedHookZygoteInit, IXposedHookLoadPackage {
[user=439709]@override[/user]
public void initZygote(StartupParam startupParam) throws Throwable {
String methodName = "installFailureToString";
XC_MethodHook hookMethod = new XC_MethodHook() {
[user=439709]@override[/user]
protected void beforeHookedMethod(final MethodHookParam param)
throws Throwable {
int result = (Integer) param.args[0];
switch (result) {
case 1:
param.setResult("BLA");
break;
case 2:
param.setResult("BLA BLA");
break;
}
}
};
final Class<?> clsPMS = XposedHelpers.findClass(
"com.android.commands.pm.Pm$1", XPm.class.getClassLoader());
XposedHelpers.findAndHookMethod(clsPMS, methodName, int.class,
hookMethod);
}
[user=439709]@override[/user]
public void handleLoadPackage(LoadPackageParam lpparam) throws Throwable {
String methodName = "installFailureToString";
if (!lpparam.packageName.equals("com.android.commands.pm"))
return;
Log.d(TAG, "com.android.commands.pm is loaded...");
XC_MethodHook hookMethod = new XC_MethodHook() {
[user=439709]@override[/user]
protected void beforeHookedMethod(final MethodHookParam param)
throws Throwable {
int result = (Integer) param.args[0];
switch (result) {
case 1:
param.setResult("BLA");
break;
case 2:
param.setResult("BLA BLA");
break;
}
}
};
final Class<?> clsPMS = XposedHelpers.findClass(
"com.android.commands.pm.Pm", XPm.class.getClassLoader());
XposedHelpers.findAndHookMethod(clsPMS, methodName, int.class,
hookMethod);
}
}
Well, there is no android.commands.pm. Not sure what you're trying to hook, but you should get the correct class name first.
PS. Please wrap your code in [CODE][/CODE] tags next time.

Hi,
sure, Sorry.
one of the things android.commands.pm.Pm is doing is to print the ADB installation message like "Failure [INVALIED_APK]"
my goal is to print my own message, so it's either by hooking the method i tried or by hooking PackageManager.class.getFields() and add my own fields.
this is the code from Pm.Java
Code:
/**
* Converts a failure code into a string by using reflection to find a matching constant
* in PackageManager.
*/
private String installFailureToString(int result) {
Field[] fields = PackageManager.class.getFields();
for (Field f: fields) {
if (f.getType() == int.class) {
int modifiers = f.getModifiers();
// only look at public final static fields.
if (((modifiers & Modifier.FINAL) != 0) &&
((modifiers & Modifier.PUBLIC) != 0) &&
((modifiers & Modifier.STATIC) != 0)) {
String fieldName = f.getName();
if (fieldName.startsWith("INSTALL_FAILED_") ||
fieldName.startsWith("INSTALL_PARSE_FAILED_")) {
// get the int value and compare it to result.
try {
if (result == f.getInt(null)) {
return fieldName;
}
} catch (IllegalAccessException e) {
// this shouldn't happen since we only look for public static fields.
}
}
}
}
}
// couldn't find a matching constant? return the value
return Integer.toString(result);
}
If it's not possible to hook this method, i understand i should add my own fields to packageManager
Thanks!
So we're talking about this? You haven't pasted the exact error but I'm guessing it's failing because you're using the wrong classloader. In initZygote, you shouldn't normally pass a classloader — just pass "null". In handleLoadPackage, use the hooked process' classloader (lpparam.classLoader).
EDIT: You can change/get a method's return value using param.setResult/param.getResult. Check the wiki for some more info.

Hi,
First of all thanks a lot!
this is the exception I'm getting when trying to initZygote and pass null as classloader:
Code:

BTW, i also tried this approach:
Code:
final Class<?> clsPm = XposedHelpers.findClass("android.content.pm.PackageManager", XPm.class.getClassLoader());
XposedHelpers.setAdditionalStaticField(clsPm, "MY_MESSAGE", 1000);
But it doesn't seem to work either...
As I said, you're using the wrong class loader.
Yes, i understand that, but which class loader should I use?
actually, which approach is better for this case? use initZygote or handleLoadPackage?
this how i did it this time:
Code:
final Class<?> clsPMS = XposedHelpers.findClass("com.android.commands.pm.Pm", null);
XposedHelpers.findAndHookMethod(clsPMS, methodName,int.class, hookMethod);
I'd use initZygote since it's more readable/shorter.
As for which class loader to use, please see post #7.
I tried that (please see post #10), is that what you meant? since i got the same exception as in post #8

You didn't indicate anything was wrong in post #10, I assumed that had worked. As usual, you should post the full code (including the initZygote/handleLoadPackage part so we know which you're using) and the exact error.
This is how you'd do it in initZygote:
Java:
public void initZygote(StartupParam startupParam) throws Throwable {
findAndHookMethod("full.class.Name", null, "methodName",
SomeArgument.class, new XC_MethodHook() {
[PLAIN]@Override[/PLAIN]
protected void afterHookedMethod(final MethodHookParam param) throws Throwable {
// Do something.
}
}
);
}
And in handleLoadPackage:
Java:
public void handleLoadPackage(final XC_LoadPackage.LoadPackageParam lpparam) throws Throwable {
if (!lpparam.packageName.equals("some.package.name"))
return;
findAndHookMethod("full.class.Name", lpparam.classLoader, "methodName",
SomeArgument.class, new XC_MethodHook() {
[PLAIN]@Override[/PLAIN]
protected void afterHookedMethod(final MethodHookParam param) throws Throwable {
// Do something.
}
}
);
}

Hi,
Strange since i do see in #10 an example (not full code...) of how i tried to do it.
anyway, I don't think that this is my problem. here is my code:
Code:
public class XPm implements IXposedHookZygoteInit {
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
String methodName = "installFailureToString";
XC_MethodHook hookMethod = new XC_MethodHook() {
@Override
protected void beforeHookedMethod(final MethodHookParam param) throws Throwable {
int result = (Integer) param.args[0];
switch(result) {
case 1:
param.setResult("BLA");
break;
case 2:
param.setResult("BLA BLA");
break;
}
}
};
final Class<?> clsPMS = XposedHelpers.findClass("com.android.commands.pm.Pm", null);
XposedHelpers.findAndHookMethod(clsPMS, methodName,int.class, hookMethod);
}
}

Not the initZygote/handleLoadPackage part, though, so I couldn't know which you're using.

So, I'm not sure I understand, can i hook it or not?
I didn't find IXposedHookCmdInit under XposedHelpers...
Thanks!

Also check post #4 in the same thread.
Basically, you could do it, but you probably don't want to since it's deprecated and disabled by default. I guess you'll want to look into hooking PackageManager instead.

I agree, so if this the method I wanted to hook (under PM):
Code:
private String installFailureToString(int result) {
Field[] fields = PackageManager.class.getFields();
for (Field f: fields) {
if (f.getType() == int.class) {
int modifiers = f.getModifiers();
// only look at public final static fields.
if (((modifiers & Modifier.FINAL) != 0) &&
((modifiers & Modifier.PUBLIC) != 0) &&
((modifiers & Modifier.STATIC) != 0)) {
String fieldName = f.getName();
if (fieldName.startsWith("INSTALL_FAILED_") ||
fieldName.startsWith("INSTALL_PARSE_FAILED_")) {
// get the int value and compare it to result.
try {
if (result == f.getInt(null)) {
return fieldName;
}
} catch (IllegalAccessException e) {
// this shouldn't happen since we only look for public static fields.
}
}
}
}
}
// couldn't find a matching constant? return the value
return Integer.toString(result);
}
I now need to hook this part:
Code:
Field[] fields = PackageManager.class.getFields();
which as i understand means to add more fields under PackageManager. is this the right way to do it? (since it didn't work for me)
Code:
final Class<?> clsPMS = XposedHelpers.findClass("android.content.pm.PackageManager", XPm.class.getClassLoader());
XposedHelpers.setAdditionalStaticField(clsPMS, "MY_KEY", 1000);
Thanks!
I have one app which can call java functions from scripts defined at runtime, but has not enough permissions to do most of the stuff, like toggling wifi.
So I tried to create a module hooking the Packagemanager to grant these permissions.
My code so far:
Code:
public class Hook implements IXposedHookLoadPackage, IXposedHookZygoteInit {
ArrayList<String> newPerms;
@Override
public void handleLoadPackage(XC_LoadPackage.LoadPackageParam loadPackageParam) throws Throwable {
if(!loadPackageParam.packageName.equals("android"))return;
final Class<?> clsPMS = findClass("com.android.server.pm.PackageManagerService", loadPackageParam.classLoader);
XC_MethodHook hookGrantPermissions = new XC_MethodHook() {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
String pkgName = (String) getObjectField(param.args[0], "packageName");
if(!(pkgName.equals(Strings.LLX)||pkgName.equals(Strings.LL)))return;
//XposedBridge.log("Package: "+pkgName);
if(newPerms == null || newPerms.isEmpty() ) return;
ArrayList<String> origRequestedPermissions = (ArrayList<String>) getObjectField(param.args[0], "requestedPermissions");
param.setObjectExtra("orig_requested_permissions", origRequestedPermissions);
//XposedBridge.log("Old Permissions "+Arrays.toString(origRequestedPermissions.toArray()));
//XposedBridge.log("New Permissions "+Arrays.toString(newPerms.toArray()));
ArrayList<String> newRequestedPermissions = new ArrayList<>(origRequestedPermissions);
newRequestedPermissions.addAll(newPerms);
//XposedBridge.log("All Permissions"+Arrays.toString(newRequestedPermissions.toArray()));
//param.args[1] = true;
[U][B]setObjectField(param.args[0], "requestedPermissions", newRequestedPermissions);[/B][/U]
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
ArrayList<String> origRequestedPermissions = (ArrayList<String>) param.getObjectExtra("orig_requested_permissions");
if (origRequestedPermissions != null)
setObjectField(param.args[0], "requestedPermissions", origRequestedPermissions);
}
};
if (Build.VERSION.SDK_INT < 21) {
findAndHookMethod(clsPMS, "grantPermissionsLPw", "android.content.pm.PackageParser$Package", boolean.class, hookGrantPermissions);
} else {
findAndHookMethod(clsPMS, "grantPermissionsLPw", "android.content.pm.PackageParser$Package", boolean.class, String.class, hookGrantPermissions);
}
}
@Override
public void initZygote(StartupParam startupParam) throws Throwable {
XSharedPreferences pref = new XSharedPreferences(this.getClass().getPackage().getName(), Strings.PREF_NAME);
pref.makeWorldReadable();
newPerms = Strings.read(pref);
}
Sidenote: Code is partially forked from Appsettings module: https://github.com/rovo89/XposedAppSettings
The problem is: when I restart my phone after enabling the module, I just get a blackscreen after the bootanimation.
When I comment out the line marked fat underlined, it works, but does nothing (because this line is essential).
I have practically no idea why this isn't working.
I know that the input returned from Strings.read is valid.
My Question: What am I doing wrong?

I am doing something similar. Maybe you can get some ideas from my PermissionGranter at:
https://github.com/GravityBox/Gravi...co/lollipop/gravitybox/PermissionGranter.java
I thought it would be better to modify the query instead of lists itself, but I'll try that out. Thanks!
Now my Hook looks like this:
Code:
XC_MethodHook hookGrantPermissions = new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
String pkgName = (String) getObjectField(param.args[0], "packageName");
if (!(pkgName.equals(Strings.LLX) || pkgName.equals(Strings.LL))) return;
Object extras = getObjectField(param.args[0], "mExtras");
Set<String> grantedPerms = (Set<String>) getObjectField(extras, "grantedPermissions");
Object settings = getObjectField(param.thisObject, "mSettings");
Object permissions = getObjectField(settings, "mPermissions");
for (String perm : newPerms) {
Object permission = callMethod(permissions, "get", perm);
if (permission == null) continue;
grantedPerms.add(perm);
int[] gpGids = (int[]) getObjectField(extras, "gids");
int[] bpGids = (int[]) getObjectField(permission, "gids");
gpGids = (int[]) callStaticMethod(param.thisObject.getClass(),
"appendInts", gpGids, bpGids);
if (BuildConfig.DEBUG) XposedBridge.log("Permission added: " + permission);
}
}
};
But checkCallingOrSelfPermsisson still fails for the added permissions...
I get the log (in fact two times) but I still don't seem to have the permissions inside of the app.
Solved it myself. If there is a shared user, it has to be used instead of normal object.
Code:
XC_MethodHook hookGrantPermissions = new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
String pkgName = (String) getObjectField(param.args[0], "packageName");
if (!(pkgName.equals(Strings.LLX) || pkgName.equals(Strings.LL))) return;
Object extras = getObjectField(param.args[0], "mExtras");
Set<String> grantedPerms = (Set<String>) getObjectField(extras, "grantedPermissions");
Object sharedUser = getObjectField(extras, "sharedUser");
if(sharedUser != null) grantedPerms = (Set<String>) getObjectField(sharedUser, "grantedPermissions");
Object settings = getObjectField(param.thisObject, "mSettings");
Object permissions = getObjectField(settings, "mPermissions");
for (String perm : newPerms) {
Object permission = callMethod(permissions, "get", perm);
if (permission == null) continue;
grantedPerms.add(perm);
int[] gpGids = (int[]) getObjectField(sharedUser!=null?sharedUser:extras, "gids");
int[] bpGids = (int[]) getObjectField(permission, "gids");
callStaticMethod(param.thisObject.getClass(),
"appendInts", gpGids, bpGids);
if (BuildConfig.DEBUG) XposedBridge.log("Permission added: " + permission);
}
}
};
@C3C076 do you know any way how to get runtime (level dangerous) permissions on Android Marshmallow?
Getting normal permissions is actually a bit easier now, but I haven't found a way for runtime permissions.
