注意：injectInputEvent 的第二个参数 sync 当被设置为 true 的时候，只可在测试框架的子线程中调用，不可在被测试者的主线程（UI线程）中调用，否则会导致被测试UI线程阻塞。原因是调用之后需要在另一个线程中等待执行结果。

Android跳转权限设置页面

最近项目上有个需求，读取通讯录。当用户点了拒绝访问通讯录或者其他权限，导致无法使用，这时候我想重新打开权限设置，但是对于很多小白用户不知道怎么设置，这就会导致用户体验不友好的一面。

之前已经有人写过类似的文章，不过都比较分散，经实测将这些方法总结了一下。

要跳转的权限设置界面如图：目前手上只有华为和小米作为测试

国产手机Android R(Android 11)系统执行Espresso UI(AndroidX)遇到的问题总结

最近在 Android R(Android 11)系统上执行以前写的Espresso UI(AndroidX)单元测试用例的时候，发现在 联想拯救者电竞手机Pro(128GB) 系统版本 12.5.225上，如果测试用例申请了通讯录写入权限，如下：

1	<uses-permission android:name="android.permission.WRITE_CONTACTS" />

那么测试用例执行的时候，会报告如下错误：

1	Test running failed:Process crashed.

详细的logcat日志如下：

目前测试发现，即使通过GrantPermissionRule授予权限，也是没用的，代码根本来不及执行，应用就一下被系统杀死了。

目前只能是不测试这部分功能。

1 2	@Rule public final GrantPermissionRule rule = GrantPermissionRule.grant(android.Manifest.permission.WRITE_CONTACTS);

在OPPO/VIVO/小米等手机上，需要手工开启 后台弹出界面权限 才能执行单元测试。有个思路是通过UI Automator来自动开启这个权限，暂时还需要测试一下。

Android R(11) ContentResolver报错java.lang.IllegalArgumentException: Invalid token limit

在Android 11执行如下代码：

/**
 * 保存拍照的图片是否已经完成
 *
 * @param context Context 对象
 * @return 查询成功返回 true ,否则返回false
 */
private static boolean isSavePictureComplete(@NonNull final Context context, long takeTime) {
    //扫描图片
    final Uri uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
    final ContentResolver resolver = context.getContentResolver();
    final Cursor cursor = resolver.query(uri, new String[]{
            MediaStore.Images.Media.DATE_ADDED, 
            MediaStore.Images.Media._ID, 
            MediaStore.Images.Media.SIZE },
            MediaStore.MediaColumns.SIZE + ">0",
            null,
            MediaStore.Files.FileColumns._ID + " DESC limit 1 offset 0");

//读取扫描到的图片
    if ((null != cursor) && (cursor.getCount() > 0) && cursor.moveToFirst()) {
        //获取图片时间
        long time = cursor.getLong(cursor.getColumnIndex(MediaStore.Images.Media.DATE_ADDED));
        int id = cursor.getInt(cursor.getColumnIndex(MediaStore.Images.Media._ID));
        if (String.valueOf(time).length() < 13) {
            time *= 1000;
        }
        cursor.close();
        // 如果照片的插入时间大于相机的拍照时间，就认为是拍照图片已插入
        return time + 1000 < takeTime; 
    }
    return true;
}

/**

* 保存拍照的图片是否已经完成

* @param context Context 对象

* @return 查询成功返回 true ,否则返回false

private static boolean isSavePictureComplete(@NonNull final Context context, long takeTime) {

//扫描图片

final Uri uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

final ContentResolver resolver = context.getContentResolver();

final Cursor cursor = resolver.query(uri, new String[]{

}

cursor.close();

// 如果照片的插入时间大于相机的拍照时间，就认为是拍照图片已插入

return time + 1000 < takeTime;

}

return true;

}

会出现如下错误：

原因为 Android 11 上使用 ContentResolver 的时候，已经不允许进行 SQL语句拼接，主要是为了防止 SQL注入攻击。

Robolectric/PowerMock测试AIDL相关类

在编写单元测试用例的时候，如果被测试类是与AIDL相关的类，不管是直接调用，还是被测试类继承了AIDL生成的类，由于AIDL类是在编译期间动态生成的，并且每次构建都会重新生成一次（类名相同，但是Hash可能会变，文件修改日期必然变更）。

然而，由于PowerMock调用Objenesis库为了加快编译速度，会缓存同名的类，这样导致在运行时进行类型转换的时候无法通过校验，报告如下错误：

org.mockito.exceptions.base.MockitoException: 
    ClassCastException occurred while creating the mockito proxy :
      class to mock : 'com.squareup.otto.Bus', loaded by classloader : 'org.robolectric.internal.bytecode.InstrumentingClassLoader@1593948d'
