有人可以给我一个有效的例子，说明如何忽略LeakCanary的某些类吗？
我在看这个示例时忽略了LeakCanary第三方库中的某些类，但是我不知道该在应用程序中的位置。我将其放在我的Application类中，但是这些变量和方法有错误：isInAnalyzerProcess，enableDisplayLeakActivity，应用程序，androidWatcher
public class DebugExampleApplication extends ExampleApplication {
protected RefWatcher installLeakCanary() {
if (isInAnalyzerProcess(this)) {
return RefWatcher.DISABLED;
} else {
ExcludedRefs excludedRefs = AndroidExcludedRefs.createAppDefaults().build();
enableDisplayLeakActivity(application);
ServiceHeapDumpListener heapDumpListener = new ServiceHeapDumpListener(application, DisplayLeakService.class);
final RefWatcher refWatcher = androidWatcher(application, heapDumpListener, excludedRefs);
registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
public void onActivityDestroyed(Activity activity) {
if (activity instanceof ThirdPartyActivity) {
return;
}
refWatcher.watch(activity);
}
// ...
});
return refWatcher;
}
}
}
最佳答案
感谢CommonsWare，可以在LeakCanary上调用方法和变量。这是一个忽略LeakCanary中某些参考或活动的完整示例。查看评论：IGNORE引用和IGNORE活动。
import android.app.Activity;
import android.app.Application;
import android.content.Context;
import android.os.Bundle;
import com.squareup.leakcanary.AndroidExcludedRefs;
import com.squareup.leakcanary.DisplayLeakService;
import com.squareup.leakcanary.ExcludedRefs;
import com.squareup.leakcanary.LeakCanary;
import com.squareup.leakcanary.RefWatcher;
import com.squareup.leakcanary.ServiceHeapDumpListener;
public class MyApplication extends Application {
// LeakCanary for memory leak detection
private RefWatcher refWatcher;
public static RefWatcher getRefWatcher(Context context) {
MyApplication application = (MyApplication) context.getApplicationContext();
return application.refWatcher;
}
@Override
public void onCreate() {
super.onCreate();
refWatcher = installLeakCanary();
}
/**
* Excluding known memory leaks from third party libraries
* @return
*/
protected RefWatcher installLeakCanary() {
if (LeakCanary.isInAnalyzerProcess(this)) {
return RefWatcher.DISABLED;
} else {
// IGNORE References: Update or add reference class and context name in instanceField
ExcludedRefs excludedRefs = AndroidExcludedRefs.createAppDefaults()
.instanceField("com.example.third.party.TheirClassOne", "context")
.instanceField("com.example.third.party.TheirClassTwo", "context")
.build();
LeakCanary.enableDisplayLeakActivity(this);
ServiceHeapDumpListener heapDumpListener = new ServiceHeapDumpListener(this, DisplayLeakService.class);
final RefWatcher refWatcher = LeakCanary.androidWatcher(this, heapDumpListener, excludedRefs);
registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
@Override
public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
}
@Override
public void onActivityStarted(Activity activity) {
}
@Override
public void onActivitySaveInstanceState(Activity activity, Bundle outState) {
}
@Override
public void onActivityPaused(Activity activity) {
}
@Override
public void onActivityStopped(Activity activity) {
}
@Override
public void onActivityDestroyed(Activity activity) {
//IGNORE Activities: Update or add the class name here to ingore the memory leaks from those actvities
if (activity instanceof ThirdPartyOneActivity) return;
if (activity instanceof ThirdPartyTwoActivity) return;
if (activity instanceof ThirdPartyThreeActivity) return;
refWatcher.watch(activity);
}
@Override
public void onActivityResumed(Activity activity) {
}
});
return refWatcher;
}
}
}
