使用context.startActivity直接向whatsapp发送消息

Question

我想通过whatsapp直接发送消息，我发现下面的代码正常工作。但是，在将代码作为常用函数调用移动到另一个java文件后，它无法正常工作并崩溃。那有什么不对？感谢

之前：

Intent sendIntent = new Intent();
            sendIntent.setAction(Intent.ACTION_SEND);
            sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
            sendIntent.setType("text/plain");
            sendIntent.setPackage("com.whatsapp");
            startActivity(sendIntent);

后：

public void share2whatsapp(Context context) {

    Intent sendIntent = new Intent(Intent.ACTION_SEND);
    sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
    sendIntent.setType("text/plain");
    sendIntent.setPackage("com.whatsapp");
    context.startActivity(sendIntent);
}

public void share2whatsapp(Context context) {
    Intent sendIntent = new Intent(Intent.ACTION_SEND);
    sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");
    sendIntent.setType("text/plain");
    sendIntent.setPackage("com.whatsapp");
    sendIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(sendIntent);
}
