20160106日补充如何下载完成后自动弹出安卓界面

思路：接收下载完成的广播，根据下载任务的ID获取APK的安装路径弹出安装界面

<receiver android:name=".receiver.DownLoadCompleteReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.DOWNLOAD_COMPLETE" />
            </intent-filter>
        </receiver>

public class DownLoadCompleteReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals(DownloadManager.ACTION_DOWNLOAD_COMPLETE)) {
            long id = PreferencesUtil.getDownLoadId();
            if (id == 0l) {
                return;
            }
            DownloadManager.Query query = new DownloadManager.Query();
            query.setFilterById(id);
            String saveFileName = null;
            Cursor cursor = FileUtils.getDownloadManager(context).query(query);
            if (cursor.moveToFirst()) {
                saveFileName = cursor.getString(cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
            }
            cursor.close();
            PreferencesUtil.clearDownLoadId();
            /** 下载完成后自动安装apk */
            if (saveFileName != null) {
                Intent intent1 = new Intent(Intent.ACTION_VIEW);
                intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                intent1.setDataAndType(Uri.parse(saveFileName), "application/vnd.android.package-archive");
                context.startActivity(intent1);
            }

        }
    }
}
