简单的Android应用-在智能手机上运行时出现内存不足错误 [英] Simple Android App - Out of Memory error when running on smartphone
问题描述
我是Android Studio的新手，我尝试制作一个简单的应用程序.单击按钮后，应显示随机图像.下一个不能是已经显示的.
I am fairly new to Android Studio and I try to make a simple app. Random Images should appear after a button is clicked. The next cannot be one that was already showed.
我有两节课. MainActivity和RandomCardDraw.
I have two classes. The MainActivity and RandomCardDraw.
当我在AVD模拟器中运行该应用程序时，它不会崩溃.但是有时我会收到跳过的帧"信息.当我在Samsung S6上运行该程序时，每次尝试获取第二张图像时，该应用程序都会崩溃.在Android中，我可以看到内存不足错误.
When I run the app in the AVD Emulator, it does not crash. But sometimes I get the information "Skipped frames". When I run it on my Samsung S6 the app crashes everytime when I try to get the second image. In Android I can see a Out of Memory Error.
图像在100-200kb之间，我大约有18张.
The images are between 100-200kb and I have about 18 of them.
也许您可以看到我从哪里获得我的性能问题?
Maybe you can see where I get my perfomance Issues from?
这是我的代码:
MainActivity:
MainActivity:
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends AppCompatActivity {
ImageView cardView;
Button nextCard;
RandomCardDraw2 game1 = new RandomCardDraw2();
int counter = 0;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
game1.createRandomCardList();
gameStart();
}
public void gameStart()
{
cardView = (ImageView) findViewById(R.id.cardView);
nextCard = (Button) findViewById(R.id.nextCard);
nextCard.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v)
{
if (counter < 19)
{
int id = getResources().getIdentifier(game1.drawnCards.get(counter), "drawable", getPackageName());
cardView.setImageResource(id);
counter++;
}
}
});
}
}
和RandowmCardDraw:
And RandowmCardDraw:
import java.util.ArrayList;
import java.util.Random;
public class RandomCardDraw2
{
ArrayList<String> drawnCards = new ArrayList<>();
Random rndInt = new Random();
public void createRandomCardList()
{
boolean gameType = true;
int counter;
if (gameType == true)
{
counter = 19;
for (int i = 0; i < counter; i++)
{
String cardId = "card" + rndInt.nextInt(18 + 1);
drawnCards.add(cardId);
}
}
else
{
counter = 23;
for (int i = 0; i < counter; i++)
{
String cardId = "card" + rndInt.nextInt(18 + 1);
drawnCards.add(cardId);
}
}
}
}
打开应用程序时.带有卡片的ArrayList是随机填充的.然后，当用户单击按钮时，将显示下一张卡片.正如我所说，当我想要获取第二张图片时，我的智能手机上的应用程序崩溃了.
When the app is opened. The ArrayList with cards is filled randomly. And then when the user clicks the button, the next card appears. As I said, on my smartphone the app crashes when I want to get the second image.

任何人都可以帮忙吗?
非常感谢！
推荐答案
将这些添加到清单中的这些行:
add these in your manifest these lines:
android:hardwareAccelerated="false"
android:largeHeap="true"
@您的manifest.xml可能是:
@your manifest.xml would like be:
<application
android:allowBackup="true"
android:hardwareAccelerated="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:largeHeap="true"
android:supportsRtl="true"
android:theme="@style/AppTheme">
