不采用第三方直接使用Intent分享，主要都是针对国外的比如FB,Line,WhatsApp,Telegram

其实系统的分享很简单，我们只要找到想要分享到的APP中的Action在加上知道包名就可以了

首先检查手机是否安装了某一项APP

public static boolean isAPPInstalled(Context context, String packageName) {    PackageManager pm = context.getPackageManager();    List<PackageInfo> pinfo = pm.getInstalledPackages(0);    for (int i = 0; i < pinfo.size(); i++) {        if (pinfo.get(i).packageName.equals(packageName)) {            return true;        }    }    return false;}

我们只要传递包名就可以了

分享代码基本都千篇一律

/** * line分享 */public void lineShare(String url, String content) {    try {        ComponentName cn = new ComponentName("jp.naver.line.android", "jp.naver.line.android.activity.selectchat.SelectChatActivity");        Intent shareIntent = new Intent();        shareIntent.setAction(Intent.ACTION_SEND);        shareIntent.setType("text/plain"); // 纯文本        shareIntent.putExtra(Intent.EXTRA_TEXT, content + " " + url);        shareIntent.setComponent(cn);//跳到指定APP的Activity        mActivity.startActivity(Intent.createChooser(shareIntent, ""));    } catch (Exception ex) {        Logger.e(TAG, "lineShare:" + ex);    }}public void whatsAppShare(String url, String content) {    try {        Intent vIt = new Intent("android.intent.action.SEND");        vIt.setPackage("com.whatsapp");        vIt.setType("text/plain");        vIt.putExtra(Intent.EXTRA_TEXT, content + " " + url);        mActivity.startActivity(vIt);    } catch (Exception ex) {        Logger.e(TAG, "whatsAppShare:" + ex);    }}public void messengerShare(String url, String content) {    try {        Intent vIt = new Intent("android.intent.action.SEND");        vIt.setPackage("com.facebook.orca");        vIt.setType("text/plain");        vIt.putExtra(Intent.EXTRA_TEXT, content + " " + url);        mActivity.startActivity(vIt);    } catch (Exception ex) {        Logger.e(TAG, "messengerShare:" + ex);    }}public void telegramShare(String url, String content) {    try {        Intent vIt = new Intent("android.intent.action.SEND");        vIt.setPackage("org.telegram.messenger");        vIt.setType("text/plain");        vIt.putExtra(Intent.EXTRA_TEXT, content + " " + url);        mActivity.startActivity(vIt);    } catch (Exception ex) {        Logger.e(TAG, "telegramShare:" + ex);    }}public void wechatShare(String url, String content) {    try {        Intent vIt = new Intent("android.intent.action.SEND");        vIt.setPackage("com.tencent.mm");        vIt.setType("text/plain");        vIt.putExtra(Intent.EXTRA_TEXT, content + " " + url);        mActivity.startActivity(vIt);    } catch (Exception ex) {        Logger.e(TAG, "wechatShare:" + ex);    }}

很简单吧，就是有的时候包名不是太好找
