Kindle HD 上的 Android BrowserActivity

Question

我有一个 Android 应用程序可以创建本地 HTML 文件，然后在浏览器中将其显示给用户。我遇到过 BrowserActivity 无法在不同设备上运行的问题，具体取决于安装的浏览器。我当前的代码执行以下操作 -

    public void displayStats()
{
    String file = produceStats();
    Uri uri = Uri.parse("file://" + file);

    // chrome ??
    Intent intent1 = new Intent(Intent.ACTION_VIEW);        
    intent1.setDataAndType(uri, "multipart/related");

    // default "Internet" browser
    Intent intent2 = new Intent(Intent.ACTION_VIEW, uri);
    intent2.setDataAndType(uri, "text/html");
    intent2.setClassName("com.android.browser", "com.android.browser.BrowserActivity");         

    // any other browser (FireFox) ??
    Intent intent3 = new Intent(Intent.ACTION_VIEW);
    intent3.setDataAndType(uri, "text/html");
    intent3.addCategory(Intent.CATEGORY_BROWSABLE);             

    PackageManager packageManager = getPackageManager();
    List<ResolveInfo> activities1 = packageManager.queryIntentActivities(intent1, 0);
    List<ResolveInfo> activities2 = packageManager.queryIntentActivities(intent2, 0);
    List<ResolveInfo> activities3 = packageManager.queryIntentActivities(intent3, 0);

    boolean isIntentSafe1 = activities1.size() > 0;
    boolean isIntentSafe2 = activities2.size() > 0;
    boolean isIntentSafe3 = activities3.size() > 0;

    List<Intent> targetedShareIntents = new ArrayList<Intent>();

    if (isIntentSafe1)
    {
        unpackResolvedIntents(uri, "multipart/related", activities1, targetedShareIntents);         
    }
    if (isIntentSafe2) {
        unpackResolvedIntents(uri, "text/html", activities2, targetedShareIntents); 
    }
    if (isIntentSafe3) {
        unpackResolvedIntents(uri, "text/html", activities3, targetedShareIntents); 
    } 

    if (targetedShareIntents.isEmpty()) {
        // go to market to install app ????
        Toast.makeText(plink.this, "Please install BROWSER to complete (Chrome)", Toast.LENGTH_LONG).show();
        Intent goToMarket = new Intent(Intent.ACTION_VIEW)
        .setData(Uri.parse("market://details?id=com.android.chrome"));
        startActivity(goToMarket);
    } else if (targetedShareIntents.size() == 1) {
        startActivity(targetedShareIntents.remove(0));          
    } else {
        Intent chooserIntent = Intent.createChooser(targetedShareIntents.remove(0), "Select viewer");
        Intent[] extraIntents = new Intent[targetedShareIntents.size()];
        for (int i = 0; i < targetedShareIntents.size(); i++) {extraIntents[i] = targetedShareIntents.get(i);}
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);

        startActivity(chooserIntent);
    }

}

produceStats() 调用返回文件路径，然后此函数的其余部分处理各种不同的浏览器，如果有多个可用浏览器，它会为用户提供一个选择器。

我的问题是，一位用户报告说，当他在装有 SILK 浏览器的 Kindle HD 设备上运行该应用程序时，应用程序崩溃了。因此，他的堆栈转储是 -

26 Jan 2014 16:26:09 GMT:Uncaught exception in java.lang.Thread:main(Unable to find explicit activity class {com.android.browser/com.android.browser.BrowserActivity}; have you declared this activity in your AndroidManifest.xml?)
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.android.browser/com.android.browser.BrowserActivity}; have you declared this activity in your AndroidManifest.xml?
at android.app.Instrumentation.checkStartActivityResult(Instrumentation.java:1624)
at android.app.Instrumentation.execStartActivity(Instrumentation.java:1418)

我的问题是 - 如何在 Kindle 上启动以在 SILK 中显示文件？谢谢

Answer 1

基于对其 list 的检查，Kindle Fire HD 上的 Slik 似乎不支持 HTML 的 file:// 方案。它似乎只支持 http://、https:// 和 inline://。我无法解释您遇到的具体崩溃，因为我没有看到 AOSP 浏览器应用程序的任何迹象，所以我不知道为什么 PackageManager 会以其他方式报告。
