ContentResolver.query() 方法抛出“无效令牌限制”错误

Question

内部版本号为 RQ1A.201205.003 或更高版本的 Pixel 设备上会出现以下错误。
\n我想知道错误原因以及如何处理。
\n这是一个错误还是规格更改？

\n

\xe2\x96\xa0code

\n

      ContentResolver resolver = getContentResolver();\n      String order = "date ASC limit 100";\n      Cursor cursor = resolver.query(\n          CallLog.Calls.CONTENT_URI,\n          null,\n          null,\n          null,\n          order);\n

\xe2\x96\xa0错误

\n

"Invalid token limit,LINE:142,Method:readExceptionFromParcel Exception:Invalid token limit"\n

\xe2\x96\xa0如果替换为以下代码，则不会出现错误。

\n

buildUpon().appendQueryParameter("limit", "100")\n

\n

\xe2\x96\xa0附加信息\n使用官方文档方法实现时，没有发生错误，但该LIMIT子句不起作用（检索了所有记录）。

ContentProvider-查询

\n

 // Request 20 records starting at row index 30.\n Bundle queryArgs = new Bundle();\n queryArgs.putInt(ContentResolver.QUERY_ARG_OFFSET, 30);\n queryArgs.putInt(ContentResolver.QUERY_ARG_LIMIT, 20);\n \n Cursor cursor = getContentResolver().query(\n       contentUri,    // Content Uri is specific to individual content providers.\n       projection,    // String[] describing which columns to return.\n       queryArgs,     // Query arguments.\n       null);         // Cancellation signal.\n

从 Android 11 开始，LIMIT应OFFSET使用 Bundle 进行检索

public Cursor query (Uri uri, 
                String[] projection, 
                Bundle queryArgs, 
                CancellationSignal cancellationSignal) 

我使用这样的解决方案，它对我有用：

import android.content.ContentUris
import android.content.Context
import android.database.Cursor
import android.net.Uri
import android.os.Build
import android.os.Bundle
