ionic inn-app-browser ERR_CLEARTEXT_NOT_PERMITTED

Zaszufladkowany do: Android — Jacek @ 16:19

To solve the problem there’s other option. in file resources/android/xml/network_security_config.xml. insert:

<network-security-config>
   <base-config cleartextTrafficPermitted="true">
       <trust-anchors>
           <certificates src="system" />
       </trust-anchors>
   </base-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain>localhost</domain>
        <domain includeSubdomains="true">192.168.7.213:8733</domain>
    </domain-config>
</network-security-config>

https://stackoverflow.com/questions/54752716/why-am-i-seeing-neterr-cleartext-not-permitted-errors-after-upgrading-to-cordo

Open the android manifest file (android/app/src/main/AndroidManifest.xml) and add
android:usesCleartextTraffic="true"

to the application tag

<application
        android:name="io.flutter.app.FlutterApplication"
        android:label="tangerine_ui"
        android:icon="@mipmap/ic_launcher"
        android:usesCleartextTraffic="true">

adb devices not found

Zaszufladkowany do: Android,Programowanie — Tagi: — Jacek @ 12:04

Very likely udev is incorrectly adding your device. I too had this problem & came across a relatively simple solution.

Find your device in lsusb

$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 8087:0a2b Intel Corp.
Bus 001 Device 002: ID 05c8:03a2 Cheng Uei Precision Industry Co., Ltd (Foxlink)
Bus 001 Device 006: ID 18d1:4ee7 Google Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Point of interest in this case:

Bus 001 Device 006: ID 18d1:4ee7 Google Inc.

Check out the corresponding device file

$ ls -l /dev/bus/usb/001/006

Likely you will see something like

crw-rw-r-- 1 root root 189, 5 Sep  8 21:47 /dev/bus/usb/001/006

This which means that the device file will be owned by the user root and the group root, which is why adb can access it as root but not as your standard user.

This can be solved by creating a new udev rule – I used /etc/udev/rules.d/51-android.rules- to add the device to the group plugdev, which adb already assumes you to be a member of (you shoukd be, check using id)

SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee7", MODE="0660",
GROUP="plugdev", SYMLINK+="android%n"

**Remember to replace the ATTR{idProduct}==”4ee7″ with your own product id that you found out in step one. ** (If your vendor isn’t Google Inc., also replace the vendor id with the one before the colon in lsusb).

Now just unplug your device and plug it back in (udev should automatically respond to the new file) and tadaa:

$ adb devices

First, you must enable the developer options:

  1. Open the Settings app.
  2. (Only on Android 8.0 or higher) Select System.
  3. Scroll to the bottom and select About phone.
  4. Scroll to the bottom and tap Build number 7 times.
  5. Return to the previous screen to find Developer options near the bottom.

Open Developer options, and then scroll down to find and enable USB debugging.

integer comparision

Zaszufladkowany do: JAVA EE — Tagi: — Jacek @ 16:43

integer comparison

-eq
is equal to

if [ "$a" -eq "$b" ]

-ne
is not equal to

if [ "$a" -ne "$b" ]

-gt
is greater than

if [ "$a" -gt "$b" ]

-ge
is greater than or equal to

if [ "$a" -ge "$b" ]

-lt
is less than

if [ "$a" -lt "$b" ]

-le
is less than or equal to

if [ "$a" -le "$b" ]

<
is less than (within double parentheses)

(("$a" < "$b"))

<=
is less than or equal to (within double parentheses)

(("$a" <= "$b"))

>
is greater than (within double parentheses)

(("$a" > "$b"))

>=
is greater than or equal to (within double parentheses)

(("$a" >= "$b"))

string comparison

=

is equal to

if [ "$a" = "$b" ]

Caution Note the whitespace framing the =.

if [ "$a"="$b" ] is not equivalent to the above.

==
is equal to

if [ "$a" == "$b" ]

This is a synonym for =.

Note The == comparison operator behaves differently within a double-brackets test than within single brackets.

[[ $a == z* ]]   # True if $a starts with an "z" (pattern matching).
[[ $a == "z*" ]] # True if $a is equal to z* (literal matching).

[ $a == z* ]     # File globbing and word splitting take place.
[ "$a" == "z*" ] # True if $a is equal to z* (literal matching).

# Thanks, Stéphane Chazelas

!=
is not equal to

if [ "$a" != "$b" ]

This operator uses pattern matching within a [[ ... ]] construct.

<
is less than, in ASCII alphabetical order

if [[ "$a" < "$b" ]]

if [ "$a" \< "$b" ]

Note that the “<” needs to be escaped within a [ ] construct.

>
is greater than, in ASCII alphabetical order

if [[ "$a" > "$b" ]]

if [ "$a" \> "$b" ]

Note that the “>” needs to be escaped within a [ ] construct.

See Example 27-11 for an application of this comparison operator.

-z
string is null, that is, has zero length

 String=''   # Zero-length ("null") string variable.

if [ -z "$String" ]
then
  echo "\$String is null."
else
  echo "\$String is NOT null."
fi     # $String is null.

-n
string is not null.

Caution The -n test requires that the string be quoted within the test brackets. Using an unquoted string with ! -z, or even just the unquoted string alone within test brackets (see Example 7-6) normally works, however, this is an unsafe practice. Always quote a tested string. [1]

Application->Application Properties. Expand the Deployment tree, click Weblogic. There is an “auto generate and synchronize WebLogic JDBC Descriptors during deployment” checkbox.
