java - 从我的 Android 应用程序启动 Viber 调用请求

Question

我列出了手机中的所有联系人，并直接从我的 Android 应用程序调用打开 Viber 应用程序的 Viber Intent 。我在网上找到了一些示例，但所有示例都太旧了，可能是几年前的事了，而且没有一个对我有用.

Uri uri = getUriFromPhoneNumber(phoneNumber, context);
    if (uri != null) {

        Intent localIntent4 = new Intent("com.viber.voip.action.CALL");
        localIntent4.setType("vnd.android.cursor.item/vnd.com.viber.voip.call");
        localIntent4.setData(Uri.parse("tel:" + uri));
        startActivity(localIntent4);

        }else {
        Toast.makeText(context, "Number is not in Viber Contacts List", Toast.LENGTH_LONG).show();
    }

我已在 androidmanifest.xml 文件中包含 read_contacts 权限。 但在此基础上总是会引发安全异常。我建议的一个解决方案是包含

activity android:name="com.ujjwalmainali.univhub.TestActivity"
        android:launchMode="singleInstance"
        android:exported="true"
        android:screenOrientation="portrait">

android:exported="true"但这对我不起作用。这里出了什么问题。我需要什么样的权限才能进行 Intent 调用。

这是异常的logcat

将此标签添加到您的 list 中:

<uses-permission android:name="android.permission.CALL_PHONE" />

对于 runTimePermission :

if (ActivityCompat.checkSelfPermission(context, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
                        ActivityCompat.requestPermissions(activityCompat, new String[]{Manifest.permission.CALL_PHONE}, 123);
                        return;
                    }
                    context.startActivity(localIntent4);

。 。 。 .

public void onRequestPermissionsResult(int requestCode, String[] permissions,
                                       int[] grantResults) {
    for (int grantResult : grantResults) {
        if (grantResult == PackageManager.PERMISSION_DENIED) {
            return;
        }
    }
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        return;
    }
    startActivity(localIntent4 );
}

localIntent4 is the intent that you are using .

编辑:

您还需要根据您的 Intent 设置此标志

            localIntent4.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
