Strings Usage

Obfuscating Resources

The plugin will obfuscate all string tags with hidden="true" as attribute.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="app_name">String Obfuscator Sample</string>
    <string name="hello" hidden="true" androidTreatment="false" containsHtml="true">
        <i>Hello <strong>there</strong></i><br></br>
        General <strong>Kenobi</strong>.
    </string>
    <string name="pattern" hidden="true">%1$s (%2$d)</string>
    <string name="snake_msg_hidden" hidden="true">\n\nla-li-lu-le-lo\n\n🐍😄🍉</string>
    <string name="hello_world_a">Hello
        World
    </string>
    <string name="hello_world_b" hidden="true">Hello
        World
    </string>
    <string name="hello_world_c" hidden="true" androidTreatment="false">Hello
World
    </string>
</resources>

Use the reveal(int id) static method to expose obfuscated strings on code:

String hello = SC.reveal(R.string.hello); // Hello there
String pattern = SC.reveal(R.string.pattern, "hi", 3); // hi (3) 

With Kotlin functions:

val hello = R.string.hello.reveal() // Hello there
val pattern = R.string.pattern.reveal("hi", 3); // hi (3) 

You can also expose strings directly on layout:

<com.stringcare.library.SCTextView
    android:text="@string/hello"
    app:reveal="true"/>

Programmatically Obfuscation

StringCare can be used for obfuscating data programmatically and read the original string where you want:

String obfuscated = SC.obfuscate("hello there");
String original = SC.reveal(obfuscated);

With Kotlin:

val obfuscated = "hello there".obfuscate();
val original = obfuscated.reveal()

Attributes

containsHtml

<string name="hello" hidden="true" containsHtml="true">
    <i>Hello <strong>there</strong></i><br></br>General <strong>Kenobi</strong>.
</string>

For printing directy on layout:

<com.stringcare.library.SCTextView
     android:text="@string/hello"
     app:htmlSupport="true"
     app:reveal="true"/>

androidTreatment

The androidTreatment attribute allows to configure the way you process strings. By default, StringCare process string resources like the Android system.

<string name="hello_world_a">Hello
    World
</string>
<string name="hello_world_b" hidden="true">Hello
    World
</string>

Hello World

The plugin can process the strings unescaping text:

    <string name="hello_world_c" hidden="true" androidTreatment="false">Hello
World
    </string>

Hello
World

For printing directy on layout:

<com.stringcare.library.SCTextView
     android:text="@string/hello_world_c"
     app:androidTreatment="true"
     app:reveal="true"/>

For use on code:

// SC.reveal(int resId, boolean androidTreatment)
String value = SC.reveal(R.string.hello_world_c, false);

For use with Kotlin:

val value = R.string.hello_world_c.reveal(false)

Java Sample

SC.init(getApplicationContext());

String password = getString(R.string.snake_msg_hidden);
String original = SC.reveal(password, Version.V3);

String message = "Snake, the password is " + password + original;

((TextView) findViewById(R.id.programmatically_obfuscation)).setText(message);
String numbers = getString(R.string.pattern, "hi", 3) + " is " + SC.reveal(R.string.pattern, "hi", 3);
((TextView) findViewById(R.id.pattern)).setText(numbers);

final SCTextView tvAuto = findViewById(R.id.auto_tv);
findViewById(R.id.btn_change).setOnClickListener(v -> {
   // button logic
   if (tvAuto.isHtmlEnabled()) {
       tvAuto.setHtmlSupport(!tvAuto.isHtmlEnabled());
   } else if (tvAuto.isRevealingValue()){
       tvAuto.setRevealed(!tvAuto.isRevealingValue());
   } else if (!tvAuto.isRevealingValue()){
       tvAuto.setRevealed(!tvAuto.isRevealingValue());
       tvAuto.setHtmlSupport(!tvAuto.isHtmlEnabled());
   }
});

boolean equals = SC.reveal(R.string.hello_world_b).equals(getString(R.string.hello_world_a));
String areEquals = "Same result: " +  equals;
((TextView) findViewById(R.id.same_value)).setText(areEquals);
