Android的Browser.BOOKMARKS_URI不能在所有设备上工作。如何找出一个给定的设备的正确URI？ [英] Android Browser.BOOKMARKS_URI does not work on all devices. How to find out the correct uri for a given device?

问题描述

我想使用Android Browser.BOOKMARKS_URI到CRUD设备的书签从我的应用程序中（的 https://play.google.com/store/apps/details?id=com.elementique.web ）

它的工作罚款大部分设备，但在一些不工作： - （

在这些设备，试图使用书签导致

  java.lang.IllegalArgumentException异常：未知的URL内容：//浏览器/书签
 

我现在明白Boookmark乌里可以比AOSP默认值不同（即，内容：//浏览器/书签）。

问：

我怎样才能在正确的书签乌里给定设备？

我已经'收集'以下URI

 私有静态最终乌里BOKKMARKS_DEFAULT = Browser.BOOKMARKS_URI; // = Uri.parse（内容：//浏览器/书签）
私有静态最终乌里BOKKMARKS_URI_CHROME = Uri.parse（内容：//com.android.chrome.browser/bookmarks）;
私有静态最终乌里BOKKMARKS_URI_SAMSUNG_S_ = Uri.parse（内容：//com.sec.android.app.sbrowser.browser/bookmarks）;
 

这是个办法名单所有可用的内容URI：在设备（内容// ...）？
如果是的话，我可以列出他们并搜索/书签串的发生，给这个URI一试。

的注意的：

我目前在如果应用程序是不是能够得到一个工作书签URI（即我自己的收藏DB，因为我需要在我的应用程序书签功能）创建回退机制的过程

解决方案

  

有没有办法为列表所有可用的内容URI（内容：// ...）？在设备

有在的 Play商店可以列出所有可用的内容：// URI在设备上。它采用 PackageManager.GET_PROVIDER

下面是搜索所有可用的内容提供商各自的类：

I am trying to use Android Browser.BOOKMARKS_URI to CRUD device bookmarks from within my app ( https://play.google.com/store/apps/details?id=com.elementique.web )

It's working fine on most of the devices, but does not work on some :-(

On those devices, trying to use bookmarks leads to

java.lang.IllegalArgumentException: Unknown URL content://browser/bookmarks

I now understand that Boookmark Uri can be different than the AOSP default value (i.e. "content://browser/bookmarks").

Question:

How can I get the correct Bookmark Uri for a given device?

I already 'collected' the following URI

private static final Uri BOKKMARKS_DEFAULT = Browser.BOOKMARKS_URI; // = Uri.parse("content://browser/bookmarks")
private static final Uri BOKKMARKS_URI_CHROME = Uri.parse("content://com.android.chrome.browser/bookmarks");
private static final Uri BOKKMARKS_URI_SAMSUNG_S_ = Uri.parse("content://com.sec.android.app.sbrowser.browser/bookmarks");

Is it a way to 'list' all available content URI (content://...) on a devices? If yes, I could list them and search for occurrence of "/bookmarks" string and give a try with this URI.

Note:

I am currently in the process of creating a fallback mechanism if the app is not able to get a 'working' bookmark URI (i.e. my own Bookmark DB since I do need a bookmark feature in my app)

解决方案

Is there a way to 'list' all available content URI (content://...) on a devices?

There's an opensource APP called "Content Provider Helper" in Play Store that can list all available content:// URI on the device. It uses PackageManager.GET_PROVIDER

Here's the respective class that searches all available content provider:

SearchProviderTask.java

package com.jensdriller.contentproviderhelper.task;

import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
import java.util.Locale;
import android.content.Context;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.content.pm.ProviderInfo;
import android.net.Uri;

public class SearchProvidersTask extends DialogAsyncTask<Uri, Void, List<String>> {
    public SearchProvidersTask(Context context) {
        super(context);
    }

    @Override
    protected List<String> doInBackground(Uri... params) {
        List<String> contentProviders = new ArrayList<String>();

        try {
            PackageManager pm = mContext.getPackageManager();
            for (PackageInfo pack : pm.getInstalledPackages(PackageManager.GET_PROVIDERS)) {
                ProviderInfo[] providers = pack.providers;
                if (providers != null) {
                    for (ProviderInfo provider : providers) {
                        contentProviders.add("content://" + provider.authority);
                    }
                }
            }
        } catch (Exception e) {
            // PackageManager has died?
            mException = e;
        }

        // Sort alphabetically and ignore case sensitivity
        Collections.sort(contentProviders, new Comparator<String>() {
            @Override
            public int compare(String lhs, String rhs) {
                return lowerCase(lhs).compareTo(lowerCase(rhs));
            }

            private String lowerCase(String s) {
                return s.toLowerCase(Locale.getDefault());
            }
        });
        return contentProviders;
    }
}
