[Q][Help Needed]Drawable.setColorFilter(a, b) not working.

Hello,
I am working on a Xposed Module and for which I require to change the Colour of a Drawable PNG to User Selected.
I am using this code :
Code:
final int mAccentColour = pref.getInt("pref_key_theme_colour_accent", R.color.predefined_theme_blue);
resparam.res.setReplacement("com.whatsapp", "drawable", "input_circle_normal", new XResources.DrawableLoader() {
@Override
public Drawable newDrawable(XResources res, int id) throws Throwable {
Drawable myIcon = modRes.getDrawable(R.drawable.scrubber_normal);
if (myIcon != null) {
myIcon.mutate().setColorFilter(mAccentColour, PorterDuff.Mode.DST_OVER);
}
return myIcon;
}
});
But it won't work. Icon gets replaced my newIcon but Color Filter is not working.

Hello, is not it better to use
Code:
myIcon.[STRIKE]mutate().[/STRIKE]setColorFilter(mAccentColour, PorterDuff.Mode.DST_OVER);
?

Or in case he needs to use mutate() to make sure only that instance of resource drawable gets state change, he should rather:
Code:
Drawable myIcon = modRes.getDrawable(R.drawable.scrubber_normal)[COLOR="Red"].mutate();[/COLOR]
if (myIcon != null) {
myIcon.setColorFilter(mAccentColour, PorterDuff.Mode.DST_OVER);
}

Thanks for replying. One of my friend told the same and it worked.
But the strange thing is that before I too tried the same but it didn't worked. I don't know what made it work at last but now am all set to go ahead.

Thanks for replying. If ever I will need to use mutate(), I will use your implementation.

Problem in Bluetooth transmitting comparisation

Hi. I want to ask some comparison problem in Android studio. I have implement a bluetooth data receiving code in Android studio to receive data from Arduino. If it receive "abcde", an audio should be play (mysound). But it can't play as expected. May I ask what is the problem in the below code? Thank you.
Arduino:
BT.println("abcde");
Android:
h = new Handler() {
public void handleMessage(android.os.Message msg) {
switch (msg.what) {
case RECIEVE_MESSAGE: // if receive massage
byte[ ] readBuf = (byte[ ]) msg.obj;
String strIncom = new String(readBuf, 0, msg.arg1); // create string from bytes array
sb.append(strIncom); // append string
int endOfLineIndex = sb.indexOf("\r\n"); // determine the end-of-line
//txtArduino.setText(strIncom);
if (endOfLineIndex > 0) { // if end-of-line,
String sbprint = sb.substring(0, endOfLineIndex); // extract string
sb.delete(0, sb.length()); // and clear
txtArduino.setText(sbprint); // update TextView
if(sbprint=="abcde"){
mySound.start();}
break;
}
};
};

[Q] How to modify memory capacity?

Hello guys,
Here is the script to get RAM capacity of a device. It's really different to other device specs that I read.
I have no idea how to hook to change it (memInfo.totalMem) .
PHP:
ActivityManager actManager = (ActivityManager) context.getSystemService(context.ACTIVITY_SERVICE);
ActivityManager.MemoryInfo memInfo = new ActivityManager.MemoryInfo();
actManager.getMemoryInfo(memInfo);
long totalMemory = memInfo.totalMem;
The system file "/proc/meminfo" also holds RAM memory info, I tried to modify this file but didn't affect.
Is there anyway to solve this problem??
Have a nice day.

You can try:
Code:
ActivityManager.MemoryInfo memInfo = (ActivityManager.MemoryInfo) XposedHelpers.newInstance(ActivityManager.MemoryInfo.class);
XposedHelpers.setObjectField(memInfo, "totalMem", 141211211L);
OR:
Code:
Constructor<?> constructLayoutParams = XposedHelpers.findConstructorExact(android.app.ActivityManager.MemoryInfo.class, Parcel.class);
constructLayoutParams.setAccessible(true);
XposedBridge.hookMethod(constructLayoutParams, new XC_MethodHook(XCallback.PRIORITY_HIGHEST) {
@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
if (param.args[0] != null) {
param.args[0] = new CustomMemoryInfo();
}
}});
CustomMemoryInfo extends MemoryInfo class, you can override super method to change "totalMem" attribute

Thank for your reply, but it doesn't work. Have you ever tried running this piece or it's just your thinking?

Here's a commented example of doing this (at least for the method that you posted):
Java:
// Hook the method getMemoryInfo from the ActivityManager class
XposedHelpers.findAndHookMethod(ActivityManager.class, "getMemoryInfo", ActivityManager.MemoryInfo.class, new XC_MethodHook() {
// We use afterHooked here because you have to modify the values *after* the method already setup the object,
// as this method take the object passed as argument and parcel the data (it's always good to check the source)
// https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/app/ActivityManager.java#2358 > which calls
// https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/app/ActivityManagerNative.java#4918
[user=439709]@override[/user]
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
// Method contructor -> public void getMemoryInfo(MemoryInfo outInfo)
// As you can see, the getMemoryInfo take a MemoryInfo object as argument
// you just have to get the object from the arguments array, and then cast
// to MemoryInfo to set the desired field
((ActivityManager.MemoryInfo) param.args[0]).totalMem = 12345678L;
((ActivityManager.MemoryInfo) param.args[0]).availMem = 87654321L;
}
});

Thank you so much :good:

how to change/replace class constants

i have a class like this

Try kooking it as early as possible (Application's onCreate() is a good place to do that):
PHP:
XposedHelpers.findAndHookMethod(>>> APPLICATION.class <<<, "onCreate", new XC_MethodHook() {
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
XposedHelpers.setStaticBooleanField(ISBuildConfig.class, "DEBUG", true);
}
}

Not possible,Xposed alters code while magisk alters files,you can't convert an Xposed module into a magisk module
