java - 例外：在 Android OREO 中的 android.graphics.drawable.AdaptiveIconDrawable.isProjected
问题描述
我在 Play 商店中有一个应用程序。我每天都会在我的应用程序中收到 NullPointerException，但我不知道它来自哪里。因为，日志不包含我创建的类中的任何行。你能帮我找出它的来源吗？

这是另一份报告。但我认为其原因与上述相同。

重要提示：它总是发生在 Android Oreo（8.0 或 8.1）设备上。顺便说一句，我有一个像下面这样的方法。它返回已安装应用程序的列表。列表的元素是“MainActivity_App”。在方法中，首先我一个一个获取应用程序的图标、包名和名称，然后使用它们创建 MainActivity_App。这段代码会出现错误吗？
private List<MainActivity_App> getInstalledApps() {
List<MainActivity_App> temp = new ArrayList<>();
List<ApplicationInfo> packs = packageManager.getInstalledApplications(PackageManager.GET_META_DATA);
ArrayList<ApplicationInfo> applistTemp = new ArrayList<>();
for (ApplicationInfo info : packs) {
try {
if (packageManager.getLaunchIntentForPackage(info.packageName) != null) {
applistTemp.add(info);
}
} catch (Exception e) {
e.printStackTrace();
}
}
chosenAppsList=new ArrayList<>();
String s=settings.getString("chosenApps","");
for (int i = 0; i < applistTemp.size(); i++) {
ApplicationInfo info = applistTemp.get(i);
String appPackageName = info.packageName;
String appName="";
Drawable icon=null;
boolean select=false;
if (s.contains(appPackageName)) {
appName = info.loadLabel(getPackageManager()).toString();
icon = info.loadIcon(getPackageManager());
select = true;
}
MainActivity_App newApp=new MainActivity_App(appPackageName, appName, icon, 0, select);
temp.add(newApp);
}
return temp;
}
还有 MainActivity_App 类。
public class MainActivity_App {
private final String appPackageName;
private final String appName;
private final Drawable appIcon;
private long usedTime;
private final boolean isSelected;
MainActivity_App(String packageName, String name, Drawable icon, long time, boolean select) {
appPackageName=packageName;
appName=name;
appIcon=icon;
usedTime=time;
isSelected=select;
}
public String getAppPackageName() {
return appPackageName;
}
String getAppName() {
return appName;
}
Drawable getAppIcon() {
return appIcon;
}
long getUsedTime() {
return usedTime;
}
boolean getIsSelected() {
return isSelected;
}
public void setUsedTime(long usedTime) {
this.usedTime = usedTime;
}
}
