Android启动WebBrowser Intent产生SecurityException

Question

我正在尝试将带有文件的URL发送到带有以下内容的web活动：

public static void startDownloadFileActivity(com.app.model.File file, String link) {
    Uri uri = Uri.parse(link);
    Intent intent = new Intent(Intent.ACTION_VIEW);
    String mime = "*/*";
    MimeTypeMap mimeTypeMap = MimeTypeMap.getSingleton();
    if (mimeTypeMap.hasMimeType(file.getMimeType())) {
        mime = file.getMimeType();
    } else if (mimeTypeMap.hasExtension(MimeTypeMap.getFileExtensionFromUrl(file.getTitle()))) {
        mime = mimeTypeMap.getMimeTypeFromExtension(MimeTypeMap.getFileExtensionFromUrl(file.getTitle()));
    }
    intent.setDataAndType(uri, mime);
    try {
        SDApplication.getInstance().getCurrentActivity().startActivity(intent);
    } catch (ActivityNotFoundException e) {
        Logger.logException(ERROR_TAG, "Can't find activity for mime " + mime + "\nReason:" + e.getMessage(), e);
        ToastUtils.showToast(getContext().getString(R.string.error_no_app_for_mime));
    }
}

但当将意图发送到web浏览器时，会得到以下信息：

Fatal Exception: java.lang.SecurityException: Permission Denial: starting Intent { act=android.intent.action.VIEW dat=http://some-stand.com:10012/... typ=*/* cmp=com.google.android.apps.docs/.doclist.documentopener.WebViewOpenActivity } from ProcessRecord{4138e78 8118:com.app/u0a322} (pid=8118, uid=10322) not exported from uid 10123

我不明白什么权限需要申请打开网址。只有一台设备会产生错误：索尼Xperia。应用程序在Android清单文件中具有互联网权限。

Answer 1

在你的AndroidManifest中检查权限。xml。

android.permission.网络
