工程包括：
- LeakCanary库代码
- LeakCanaryDemo示例代码
使用步骤：
-
将LeakCanary import 入自己的工程
-
添加依赖：
compile project(':leakcanary') -
在Application中进行配置
public class ExampleApplication extends Application { ...... //在自己的Application中添加如下代码 public static RefWatcher getRefWatcher(Context context) { ExampleApplication application = (ExampleApplication) context .getApplicationContext(); return application.refWatcher; } //在自己的Application中添加如下代码 private RefWatcher refWatcher; @Override public void onCreate() { super.onCreate(); ...... //在自己的Application中添加如下代码 refWatcher = LeakCanary.install(this); ...... } .....
}
```
- 在Activity中进行配置
public class MainActivity extends AppCompatActivity {
......
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//在自己的应用初始Activity中加入如下两行代码
RefWatcher refWatcher = ExampleApplication.getRefWatcher(this);
refWatcher.watch(this);
textView = (TextView) findViewById(R.id.tv);
textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startAsyncTask();
}
});
}
private void async() {
startAsyncTask();
}
private void startAsyncTask() {
// This async task is an anonymous class and therefore has a hidden reference to the outer
// class MainActivity. If the activity gets destroyed before the task finishes (e.g. rotation),
// the activity instance will leak.
new AsyncTask<Void, Void, Void>() {
@Override
protected Void doInBackground(Void... params) {
// Do some slow work in background
SystemClock.sleep(20000);
return null;
}
}.execute();
}
}
- 在AndroidMainfest.xml 中进行配置,添加如下代码
<service
android:name="com.squareup.leakcanary.internal.HeapAnalyzerService"
android:enabled="false"
android:process=":leakcanary" />
<service
android:name="com.squareup.leakcanary.DisplayLeakService"
android:enabled="false" />
<activity
android:name="com.squareup.leakcanary.internal.DisplayLeakActivity"
android:enabled="false"
android:icon="@drawable/__leak_canary_icon"
android:label="@string/__leak_canary_display_activity_label"
android:taskAffinity="com.squareup.leakcanary"
android:theme="@style/__LeakCanary.Base" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
