Android aufblasen verursacht java.lang.OutOfMemoryError occaionally

Question

Der Code wie die in onResume einer Aktivität finden:

for (int i = 0; i < 4; i++) { 
    LayoutInflater.from(this).inflate(R.layout.image_view, gridLayout); 
    ... 
} 

Die Komponente der Layout-image_view dem Absturz im Zusammenhang ist folgende:

<ImageView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:layout_gravity="center" 
    android:layout_margin="0dip" 
    android:padding="0dip" 
    android:scaleType="centerCrop" 
    android:src="@drawable/ic_launcher_background" /> 

Die Auflösung der Image-Datei ic_launcher_background.png beträgt 399x399.

Die gelegentliche Crash-Bericht ist die folgende:

Ich möchte betonen, dass dies geschieht selten, aber es kann nicht von der catch-Block des Codes aufgefangen werden, so stürzt die App.

Könnte irgendjemand etwas Licht darauf werfen?

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.example.chingjing.myapplication"> 

    <application 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher" 
     android:label="@string/app_name" 
     android:largeHeap="true" //Add this 
     android:roundIcon="@mipmap/ic_launcher_round"

Ursache von "java.lang.OutOfMemoryError" ich dieses Problem noch nie konfrontiert, hoffen, können Sie helfen ...

1. "android:largeHeap=true" in Ihrer Manifeste Datei einstellen. (der einfachste Weg, um den OOM-Fehler zu lösen)
2. Versuchen Sie, ein kleineres Bild zu verwenden, wenn es sich um ein Speicherproblem handelt.
