HuoLaLa unify hook lib

简体中文

The HuoLaLa and Lalamove Android project employs inline-hook techniques to address system-level issues and enhance app's overall stability or performance.

Thread Shield

Safe to suspend thread.

Avoid suspending thread timeout to make process kill by Abort signal.

• Android [5,11] : Hook ThreadSuspendByPeerWarning() to modified log level, if hit thread suspend timeout, will call suspendThreadTimeout() to notified java side.

• Android [12,14] : Hook SuspendThreadByPeer() function and replace it to call SuspendThreadByPeerId() function, will not need to call suspendThreadTimeout() to notified java side, because if thread suspend timeout can not send abort signal.

• Android 15 : Hook StringPrintf() function and block thread to wait thread suspends finish, will call suspendThreadTimeout() to notified java side.

Earnings

In Lalamove Side, the number of thread suspend timeout crash times is so huge.

How to use

1. Add dependencies

    dependencyResolutionManagement {
        repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
        repositories {
            google()
            mavenCentral()
            maven { url = uri("https://jitpack.io") }
        }
    }

    dependencies {
	    implementation 'com.github.HuolalaTech:hll-sys-hook-android:1.4-SNAPSHOT'
    }

2. Add code

    SuspendThreadSafeHelper.getInstance()
            .suspendThreadSafe(object : SuspendThreadSafeHelper.SuspendThreadCallback {
                override fun suspendThreadTimeout(waitTime: Double) {
                    Log.i("TAG", "Waitting for thread suspend done, spend : $waitTime s")
                }

                override fun onError(errorMsg: String) {
                    Log.e("TAG", "onError: $errorMsg")
                }
            })
