to use startActivity post message to Line

Line跟facebook一樣在安裝了 Line/Facebook app後, 可以簡單的利用startActivity來進行一些簡單的PO文動作, 也就是藉由他本身的app去執行api。
相反來說, 若是想利用自己的app去發request 就要去add naver/facebook 的library, 這樣能做到的事更多, 但是較為麻煩。

這邊將介紹如何透過簡單的方式來PO文到line上

//判斷是否安裝了line

private boolean checkLineInstalled(){

PackageManager pm = getPackageManager();

m_appList = pm.getInstalledApplications(0);

boolean lineInstallFlag = false;

for (ApplicationInfo ai : m_appList) {

if(ai.packageName.equals(PACKAGE_NAME)){

lineInstallFlag = true;

break;

}

}

return lineInstallFlag;

}

//PO文字

public static final String PACKAGE_NAME = "jp.naver.line.android";

public static final String CLASS_NAME = "jp.naver.line.android.activity.selectchat.SelectChatActivity";

Intent intent = new Intent(Intent.ACTION_SEND);

intent.setClassName(PACKAGE_NAME, CLASS_NAME);

intent.setType("text/plain");

intent.putExtra(Intent.EXTRA_TEXT, sendText);

startActivity(intent);

//PO圖片

String fname = "send_image.jpg";

String fileFullPath = Environment.getExternalStorageDirectory().getAbsolutePath()

+ File.separator + fname;

Uri uri = Uri.fromFile(new File(fileFullPath));

Intent intent = new Intent(Intent.ACTION_SEND);

intent.setClassName(PACKAGE_NAME, CLASS_NAME);

intent.setType("image/jpeg");

intent.putExtra(Intent.EXTRA_STREAM, uri);

startActivity(intent);
