我有安装了多个浏览器的Android手机,我可能会也可能不会将浏览器设置为默认值。
所以,我的问题是......
答案 0 :(得分:6)
从我的应用程序中,如何强制仅在NATIVE android中打开链接 浏览器?
Intent intent = new Intent();
ComponentName comp = new ComponentName("com.google.android.browser","com.google.android.browser.BrowserActivity");
intent.setComponent(comp);
intent.setAction("android.intent.action.VIEW");
intent.addCategory("android.intent.category.BROWSABLE");
Uri uri = Uri.parse(url);
intent.setData(uri);
try
{
startActivity(intent);
}
catch (Exception e)
{
e.printStackTrace();
}
我是否有办法知道浏览器是否设置为默认值?
PackageManager packageManager = getPackageManager();
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("URL"));
List<ResolveInfo> list = packageManager.queryIntentActivities(intent, 0);
if (list.size() > 0) {
for (ResolveInfo resolveInfo : list) {
resolveInfo.isDefault();// will let u know if the app is set to default
}
} else {
//No apps available
}

您必须进行以下操作才能调用本机浏览器
intent.setComponent(new
componentName("com.android.browser","com.android.browser.BrowserActivity"));
答案 2 :(得分:1)
尝试这样的事情。
try {
Intent i = new Intent();
ComponentName comp = new ComponentName("com.google.android.browser","com.google.android.browser.BrowserActivity");
i.setComponent(comp);
i.setAction("android.intent.action.VIEW");
i.addCategory("android.intent.category.BROWSABLE");
ContentURI uri = new ContentURI(url);
i.setData(uri);
startActivityForResult(i, 2);
} catch (URISyntaxException e) {
e.printStackTrace();
}
对于第二个问题,您可以使用PackageManager
。
获取PackageManager
PackageManager packageManager = getPackageManager();
并查询Intent
的具体操作,数据和类别。
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("URL"));
List<ResolveInfo> list = packageManager.queryIntentActivities(intent, 0);
for (ResolveInfo resolveInfo : list) {
if(resolveInfo.isDefault())
{
//default browser
}
}

终于明白了。 resolveActivity与PackageManager实例上的MATCH_DEFAULT_ONLY标志一起使用..

当包名称因制造商而异时,可能会发生ActivityNotFoundException。 请参考这个答案,希望它会有所帮助。
答案 5 :(得分:0)
检查此代码:
private final static List<ComponentName> browserComponents = new ArrayList<ComponentName>() {{
add(new ComponentName("com.google.android.browser", "com.google.android.browser.BrowserActivity"));
add(new ComponentName("com.android.browser", "com.android.browser.BrowserActivity"));
add(new ComponentName("com.android.chrome", "com.google.android.apps.chrome.IntentDispatcher"));
}};
public static void openInNativeBrowser(Context context, String url) {
if (context == null || TextUtils.isEmpty(url)) {
return;
}
PackageManager pm = context.getPackageManager();
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.addCategory(Intent.CATEGORY_BROWSABLE);
intent.setData(Uri.parse(url));
for (ComponentName cn : browserComponents) {
intent.setComponent(cn);
ActivityInfo ai = intent.resolveActivityInfo(pm, 0);
if (ai != null) {
aLog.w(TAG, "browser: " + ai);
context.startActivity(intent);
return;
} else {
aLog.w(TAG, "can't resolve activity for " + intent);
}
}
// no native browser
intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
List<ResolveInfo> list = pm.queryIntentActivities(intent, 0);
if (list.size() > 0) {
for (ResolveInfo ri : list) {
aLog.w(TAG, ri + " : " + ri.isDefault);
}
context.startActivity(intent);
} else {
aLog.w(TAG, "no browser apps");
}
}
