着信を聞く受信機があります。このレシーバーから、(Android Intent を使用して) メールを送信するサービスを開始していますが、例外が発生しています (Log Cat のログを参照してください)。

java.lang.RuntimeException: Intent { cmp=com.pack.android.email.service/com.pack.android.service.EmailService } でサービス com.pack.android.service.EmailService@40519818 を開始できません: android.util .AndroidRuntimeException: アクティビティ コンテキストの外部から startActivity() を呼び出すには、FLAG_ACTIVITY_NEW_TASK フラグが必要です。これは本当にあなたが望むものですか？

「FLAG_ACTIVITY_NEW_TASK」と「FLAG_FROM_BACKGROUND」を設定しました。これはユーザー アクティビティではありません。インテント INTENT.SENDTO/SEND を使用して既存のアクティビティ (電子メールの送信) を開始しようとしています。

奇妙なことはエラーでした: 原因: android.content.ActivityNotFoundException: Intent を処理するアクティビティが見つかりません { act=android.intent.action.SENDTO flg=0x10000004 (エクストラがあります) }

ここで何が欠けていますか?

Java Mail API を使用してメールを送信しているときに直面したもう 1 つの問題は、メールが適切に送信されていたことですが、どういうわけかメールがメールボックスに表示されないようです。以下のリンクを参照して、意図せずに電子メールを 送信します : 意図せずに電子メールを送信する

誰かがこれについていくつかの洞察を与えることができれば、それは素晴らしいことです。

コードは次のとおりです。 Call Receiver :-

public class CallReceiver extends BroadcastReceiver
{
    private static final String LOG_TAG = "CallReceiver";
    private static final String ACTION = "android.intent.action.PHONE_STATE";

    @Override
    public void onReceive(Context context, Intent intent)
    {
        System.out.println("--------Inside onReceive of CallReceiver--------");
        Log.d(LOG_TAG, "Inside onReceive");

        if(intent.getAction().equals(ACTION)){
            Log.d(LOG_TAG, "-----Criteria matched-----");
            Intent emailIntent = new Intent(context, EmailService.class);
            emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            emailIntent.addFlags(Intent.FLAG_FROM_BACKGROUND);

あなたが得る理由

android.content.ActivityNotFoundException: No Activity found to handle Intent { 
    act=android.intent.action.SENDTO flg=0x10000004 (has extras) }

インテントにデータを設定したことがないためです。Androidは、アクション「SENDTO」とユーザーが提供するデータを処理できるアクティビティを見つけようとします。ただし、データを提供しなかったため、適切なアクティビティを見つけることができません。あなたはこのコードを持っています：

Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
emailIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
emailIntent.addFlags(Intent.FLAG_FROM_BACKGROUND);
//  emailIntent.setType("plain/text");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
            new String[] { "24adithya@gmail.com" });
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
            "Email from Intent");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,
            "Hi, This is 5554 from intent");
//  getApplicationContext().startActivity(Intent.createChooser(emailIntent, "Send mail..."));
Log.d(LOG_TAG, "context = " + getApplicationContext());
startActivity(emailIntent);

ただし、 intent.setType（）`を呼び出すemailIntent.setdataAndType()かemailする必要があります。emailIntent.setData()1 and

Log の次の行を見てください。

android.util.AndroidRuntimeException: アクティビティ コンテキストの外部から startActivity() を呼び出すには、FLAG_ACTIVITY_NEW_TASK フラグが必要です。これは本当にあなたが望むものですか？

これは、サービスからアクティビティを開始するには FLAG_ACTIVITY_NEW_TASK が必要であることを明確に示しています。だから追加

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_FROM_BACKGROUND);

サービスから活動を開始するため

使用するFLAG_ACTIVITY_NEW_TASK

Intent myIntent = new Intent(getBaseContext(), myActivity.class);
myIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_FROM_BACKGROUND);
getApplication().startActivity(myIntent);
