我有一个奇怪的Android权限拒绝,这是它:

java.lang.SecurityException: Permission Denial: isUserRunning() from pid=1078, uid=10284 requires android.permission.INTERACT_ACROSS_USERS

我还没有发现任何关于android.permission.INTERACT_ACROSS_USERS只android.permission.INTERACT_ACROSS_USERS_FULL

这是完整的logcat:

我已将此添加到我的清单中:

<permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL" android:protectionLevel="signature"/>

我正在尝试在我的自定义启动器上安装图标包,我已经阅读了这个说明如何安装图标包但我无法理解如何使用该类,这就是我所做的:

IconPackManager ic = new IconPackManager();
HashMap<String, IconPackManager.IconPack> map = new HashMap<String, IconPackManager.IconPack>(ic.getAvailableIconPacks(false));
Iterator it = map.entrySet().iterator();
Drawable d = null;
String packName = null;
IconPackManager.IconPack packIcon = null;
    while (it.hasNext()) {
       Map.Entry pair = (Map.Entry)it.next();
       packName = (String)pair.getKey();
       packIcon = (IconPackManager.IconPack)pair.getValue();
       d = packIcon.getDrawableIconForPackage(packName, iconDrawable);
       setIcon(d);
    }

我正在使用带有viewpager的CollapsingBarLayout,并且viewpager的片段具有listview,gridview.

我需要让用户使用Android 6.0拍摄照片(来自图库或相机应用).

因为我不需要控制相机,所以我想使用这里描述的意图:

但是,如果您不需要此类控件,则可以使用ACTION_IMAGE_CAPTURE意图来请求图像.当您启动意图时,系统会提示用户选择相机应用程序(如果还没有默认的相机应用程序),该应用程序将拍摄照片.相机应用程序将图片返回到应用程序的onActivityResult()方法.

https://developer.android.com/preview/features/runtime-permissions.html

但是对于这个ACTION_IMAGE_CAPTURE,你需要将额外的"MediaStore.EXTRA_OUTPUT"这个Uri 填充到一个临时文件中(没有这个参数我将只有一个缩略图).此临时文件必须位于外部存储中(可由相机应用程序访问).您需要WRITE_EXTERNAL_STORAGE权限才能在外部存储上创建文件.

因此,如果没有android.permission.CAMERA或android.permission.WRITE_EXTERNAL_STORAGE 权限,则无法通过原生对话框/应用程序捕获图像.那是对的吗？

谢谢

每次我尝试运行配置了JSP的spring boot应用程序时都会出现此错误:

我试过运行示例:spring-boot-sample-web-jsp和spring-boot-sample-web-jsp

这些样品的结果是相同的.我使用IntelliJ IDEA运行应用程序并且没有IDEA为什么它不起作用.

我试图使用漂亮的cheesesquare项目在android中实现一个材质可滚动的表单

但是当我尝试将一个EditText添加到NestedScrollView时,当keybord打开时,工具栏似乎取消固定(在没有输入的情况下没有按预期工作).

我正在尝试使用proguard来混淆代码,所以我minify在发布版本类型中启用了:

buildTypes {
    debug {
        minifyEnabled false
    }
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt')
    }
}

但是当我生成'release apk'并且在我安装它之后,应用程序运行速度变慢(滞后)..为什么在启用minify时会发生这种情况？这是我的依赖:

dependencies {
    compile 'com.android.support:support-v4:25.3.1'
    compile 'com.android.support:recyclerview-v7:25.3.1'

我正在尝试备份/还原我的应用程序的共享首选项，我使用Android备份服务执行了以下步骤：

在Manifest.xml在<application>标签

<meta-data android:name="com.google.android.backup.api_key" android:value="My Key" />

添加了此类：

public class MyBackupAgent extends BackupAgentHelper {

    // The name of the SharedPreferences file
    static final String PREFS = "my_preferences";


    @Override
    public void onCreate() {
        SharedPreferencesBackupHelper helper = new SharedPreferencesBackupHelper(this, PREFS);
        addHelper(Utilities.SETTINGS_KEY, helper);
    }

}

当将值设置为共享首选项时，我这样做：

BackupManager backupManager = new BackupManager(context);
backupManager.dataChanged();

但是，如果我卸载/重新安装应用程序，更改将不适用...
