erkennen Speicherverlust von MAT

Question

Ich benutze Memory-Analyzer-Tool, um mögliche Speicherleck in meiner Anwendung zu erkennen und unten ist das Bild von Heap-Profil, das heißt ich habe 5 Objekt der IntroActivity unter ist mein Code für Introaktivität ich bin nicht in der Lage zu finden, von wo diese Objekte mehrfach

public class IntroActivity extends AppCompatActivity {

kann, ist jemand bitte appriciated

Answer 1

keine jede mögliche Hilfe mögliches Leck finden in erstellt werden helfen, Sie haben nicht 5 Objekte von IntroActivity.
Heap-Profil besagt, dass es eine Instanz von IntroActivity und 4 Instanzen gibt, die die innere Klasse von IntroActivity darstellt.
Inner Klassen sind darunter einschließlich anonymer Klasse.

btnNext.setOnClickListener(new View.OnClickListener() { 
    ... 
} 

btnNext.setOnClickListener(new View.OnClickListener() { 
    ... 
} 

ViewPager.OnPageChangeListener viewPagerPageChangeListener = new ViewPager.OnPageChangeListener() { 
    ... 
} 

public class MyViewPagerAdapter extends PagerAdapter { 
    ... 
}
