Android Studio - Activity 图像使模拟器崩溃但在 phone 中工作

Question

我在我的 Android 工作室中添加了一个新的 Activity。这个Activity有图。这是我的 xml.file

的代码

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:showIn="@layout/auxguide1"
tools:context=".AuxGuide1">

<ImageView
    android:layout_width="200dp"
    android:layout_height="200dp"
    android:id="@+id/imageView2"
    android:src="@drawable/logoauxguide"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true" />

这是我的 java class 代码包裹 com.example.gonalo.meu;

import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;

public class AuxGuide1 extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.auxguide1);
        int secondsDelayed = 1;
        new Handler().postDelayed(new Runnable() {
            public void run() {
                startActivity(new Intent(AuxGuide1.this, MainActivity.class));

                finish();
            }
        }, secondsDelayed * 4000);
    }

}

它在我的 phone 中完美运行，但是当我运行在模拟器上它显示 "sorry the application has stopped"

这是我的logcat

它不会停止我在项目上的工作，但了解为什么会这样对我很有用。将不胜感激帮助。

Answer 1

如果 android 设备必须显示图像，它必须将整个图像加载到内存中。在您的情况下 logoauxguide 是高分辨率图像，因此整个图像将不适合设备内存。因此 OutOfMemoryError 会发生。

但是内存更大的设备，在这种情况下，您的 phone 将能够将图像加载到内存中。

如果要显示图像，必须在任何图像编辑工具中降低其分辨率（640x480 就可以）。此外，您不希望更高的内存映像增加您的 apk 大小:)
