为什么 LeakCanary 甚至在 activity 刚刚启动后就报告每个 activity 的字段泄漏？
Why LeakCanary reports about leak of each activity's field even right after activity was just started?
例如，我有以下用于自定义应用程序的代码 class（到项目中的 'activate' LeakCanary）
public class MyApp extends Application {
private RefWatcher refWatcher;
@Override
public void onCreate() {
super.onCreate();
if (LeakCanary.isInAnalyzerProcess(this)) {
// This process is dedicated to LeakCanary for heap analysis.
// You should not init your app in this process.
return;
}
refWatcher = LeakCanary.install(this);
}
public void watch(Object o) {
refWatcher.watch(o);
}
}
我有以下 activity:
public class LeakActivity extends AppCompatActivity {
private String str;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_memory_leak);
str = "Pam Pam";
((MyApp)getApplication()).watch(str);
}
}
每次 activity 在配置更改（屏幕旋转）后启动或重新创建时，我都会看到来自 LeakCanary 的通知 'str' 泄漏
Could not dump heap, previous analysis still is in progress.

有什么想法或解释为什么会这样吗？
看来这个问题与我对如何使用 LeakCanary 的不完整理解有关。此处解释了此问题（和解决方案）的原因
例如，我有以下用于自定义应用程序的代码 class（到项目中的 'activate' LeakCanary）
public class MyApp extends Application {
private RefWatcher refWatcher;
@Override
public void onCreate() {
super.onCreate();
if (LeakCanary.isInAnalyzerProcess(this)) {
// This process is dedicated to LeakCanary for heap analysis.
// You should not init your app in this process.
return;
}
refWatcher = LeakCanary.install(this);
}
public void watch(Object o) {
refWatcher.watch(o);
}
}
我有以下 activity:
public class LeakActivity extends AppCompatActivity {
private String str;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_memory_leak);
str = "Pam Pam";
((MyApp)getApplication()).watch(str);
}
}
每次 activity 在配置更改（屏幕旋转）后启动或重新创建时，我都会看到来自 LeakCanary 的通知 'str' 泄漏
